Absolutely a Bargain! I have been using this jack hammer for close to a year on various projects at home--breaking up an asphalt driveway, breaking through underground rock, etc. and have never been disappointed. Will it last forever?--probably not, but it should give me several years of dedicated service. The 45 lb. weight is heavy, but manageable. At 73, I can still handle the jack hammer with no problem, but it might not be the case for everyone. The jack hammer comes in a nice heavy-duty case. I ordered three bits for it, but have mainly used the flat 1-ich edge bit. In the fine print of some other reviews, Shell Rotella T1 SAE 40 Heavy Duty Engine Oil was recommended, which I purchased at our local auto parts store. I have yet had to add any oil though. Just keep an eye on the oil level through the small round window. Like most items, a low review is likely due to someone not reading the instructions or not caring for the jack hammer properly. An example: Putting the bit in is tricky, as one has to pull the metal piece on the side of the hammer barrel out and twist 180 degrees in order for the bit to slide in all the way, then pull the small metal piece out again and reverse to the original position. It takes a bit pf practice to master. Once the bit is in, you are good to go. Just watch the oil level. Is the hammer noisy?--Yes, but it is a jack hammer. Be sure to wear your hearing protection. I am thinking of ordering a second of these jack hammers before the prices go up due to the tariffs.

I bought the 2200 watt jack hammer to break theough the basement concrete floor to install a backwater valve to prevent any sewage from ever backing up. The price of the 2200 watt jack hammer was about the same as two days rental at the big box store's, so the price is right. I read on line to let the jack hammers weight do the work, this is almost completely correct. When starting, one must apply a slight downward pressure initially, or it will bounse all around; then let the weight do its job. Once that was figured out, it was easy to use. The case is overall a good case; however, the latches tend to get knocked off. The case definitely makes it easier to store. The bits are 1-1/8" hex, so they are more popular/readily available than the smaller jack hammers. If using it to compact dirt, the compacting bit is on the expensive side, so for what I needed, the old foot stomp method worked quite well. Be sure to add the oil prior to first use by unscrewing the site gauge. I used a purple 40 weight synthetic brand of oil, actually I think it was a 15w-40w. There a little leakage down the bit, but I think that would be expected to keep it lubricated and cool during use. When grabbing the bit after use, it will get the black dirty oil over the glove/hand, so take the necessary precautions. Some people claim it won't hold the bit in, and I also wondered how to do it ubutuakkt. Here's how, after sliding the bit in, there is a spring loaded knob which is pulled out and rotated 180 degrees to lock it in. To remove the bit, just rotate the knob 180 degrees again. In addition, like others have commented, it it doesn't start hammering when initilly pulling the switch, raise the jack and let it smack down on the concrete, and it will work just fine. Considering everything, it is a great value and you probably won't go wrong if a jack hammer is needed... . . Now what other project can I think of to use this for?

We in the process of replacing rotted 6×6 wood posts which are set in concrete. On day one I rented a big Makita jack hammer. Working and controlling that 80 lbs tool at below ground level proved to be challenging, with the biggest problem being the Makita's bits kept repeatably getting stuck, which required a lot of strength or removing the bit to get it freed up. One day's rental cost in my area was about $140. I bought this compact jack hammer based on the good reviews and I could,not be happier. For what we are doing, it is a much better tool. It is easier to control, does not get stuck as much and when it does, it is much easier to get it free. We are able to break the concrete faster with it. Mind you, we are working below ground level. The concrete starts about a foot deep and goes down about a foot or so. I also used it to break up part of a calichie (crushed limestone) RV pad. We had done this previously with a pick axe and a 6' impact bar and it was a nightmare. That compacted limestone was almost as hard a concrete. With this jack hammer, in 15 minutes I did what would take 2 or 3 hours of very hard work. I read that some people complain about oil leaks. Yes, there is some oil coming out where the bit is mounted and the top portion of the bit will be coated with oil. No big deal. Grab a paper towel and wipe the bit off once you are finished and have removed it. The case the tool comes with is nice too. The gloves are cheap but useable. The gogles are almost a throw away item, but if you don't have eye protection, they will work in a pinch. So far the tool has about 20 hours of use on it and has already more than paid for itself. Don't forget to fill it with oil before you start using it and check oil level each day you are ready to use it. November 16th 2023 update - still going strong. This tool has seen lots of use over the last 10 weeks and still working great. We always check the oil level before use. For the work that we use it for it is much better then a full size jackhammer. For the price, if it failed today, I would order another one immediately.

Great Value, a real workhorse, have busted all the ledge we intended for it (and then went on to bust alot more, 'cause it did work really, really well power-wise, so why not tackle that other ditch you weren't going to bother with?) BUT, it will not accept any other bit except those sold by Xtremepower... So, while I do very much recommend the tool, don't buy it unless the bits you need are available from Xtremepower. I've tried Bosch, DeWalt and Milwaukee bits and none of those will fit (they're all 65A spec which has a hex shank that is straight for the entire length of the head-end whereas this tool will only accept a bit that has a specific taper at the very top and while you could probably grind that in, I believe the top of the shank is hardened and you would lose the advantage of that hardening which is at least one of the reasons you're buying a more expensive bit). Also, again while I very much recommend this tool you should know that using the very simple and minimally designed power switch for more than an hour or two is detrimental to that finger. Even after a month (after about 10-15 hours of use) and my trigger finger is still numb deep into the finger. Use heavy padded gloves and maybe even some extra finger tip padding or an alternate trigger mechanism if you want to avoid a long recovery for your trigger finger. Next I'd point out the side-handle, the "D" handle, is sufficient but not much more than that. It's construction has sharp edges and cotter pins sticking out and is easily one of the cheaper components of the tool. However, as noted, it is sufficient in that you can use it effectively to control the placement of the tool, it gets the job done. Just don't expect any more than that, it is very basic and barely comfortable to use but, again, it is sufficient enough to get the job done. Other than these caveats, for the price and the power and so far, the longevity of the tool, you should feel comfortable investing the $150 or so,

This is working effectively! Value for money, it was easy to assemble, the size is manageable. I love the way it is designed, it came in a case to protect it. The speed is very good and the power is strong.

I bought this to break up sandstone and hard red clay. I was killing myself trying to do this with a pick. At this price, I figured why not. It powered through the sandstone and clay, and a bit of concrete. I bought extra oil, but it had enough to get through my job with what came in the tool. Seems reasonably well built. It's a bit heavy, but I suspect it would not be as effective if it wasn't. The square point chisel worked best for my use. I wish I had bought a spade point chisel. That would probably have worked even better for most of it, but the sandstone was pretty tough, so I would have needed to switch back to the square point chisel for that. Can't really speak to the reliability of this, but at this price, it is worth it to buy for small jobs. I'll probably get a ground rod driver for that job as well. Some people have complained about Chinese chisels being too large for the name brand hammers. These are advertised to be 1 1/8" or 1.125". In actuality, the size of the hex part of the bits that came with this, is a bit bigger than that. Mine measured about 1.173". Not sure what the Chinese are using for measuring! Anyway, this tool should handle the other Chinese bits.

Unbeliveable. My $1,400 Bosch tanked after 10 years. Got this until I could find parts for old Bosch. Not looking for repair parts now. This thing is impressive. Busted up an 8ft wide by 100ft 4in deep drive in 2 days by myself at the age of 50. Yes bits are hardened. It has a 15 amp plug even though it says 2200 watts. According to kil-o-watt it pulls 1870 watts@120 volts. Make sure you use a 12ga extension cord for runs up to 100ft. Tried it on my 14ga but voltage drop was severe and strained tool. What it nice is this design has time out of patent so anyone can build it now. It is the same design my grandfather used in the 1960s. Yes it's old school but buy a set of welder gloves to "soften" the blows. Really $159? Remember also to add oil it comes only with a drop of test oil you will burn it out if you don't. Manual says shell rotella which is Diesel engine oil 40w. Came with retightning wrench, oil sight glass removal tool for oil. Very sharp blunt tip bit and 1 1/2 wide spade bit. Sorry for long review but these were answers I looked for before buying. The only drawback is the case it is very cheap plastic and arrived cracked but I don't need it. Blow force is actually 37 to 41 pounds quite impressive. Becareful when using it is very easy especially after you tire to rest tool against leg blocking air cool intake heating motor up fast. Anyway for you Union guys that will bark at me for getting this (I have spent thousands over the years buying american when possible) this hammer does what the $900 hammers do. Laughing all the way to the bank.

There are definitely some problems - mostly ergonomic. Let me start though by saying it works well for the price. Cheaper than renting after a couple of uses. Why the 3 stars then? The first star is lost because it's sold as a 2200 watt tool. It's not even close. I measured it with a Kill-A-Watt meter and though I can't remember exactly, I think it was around 1700 watts. That's a huge difference! People buy things based on power so technically that is a word that starts with "F" and rhymes with broad (I can't type it here because Amazon won't let you do say that even though it's a clear case, legally and by any other sense). This is a recurring problem with tools made in this country. The other star is lost because it is not ergonomically correct. What the "designers" (copiers?) have done is take the design for a small horizontal hammer and scaled it up, thinking that will be OK. But this will be used 99% of the time in the vertical mode. The trigger handle is not shaped well for this, nor is the helper handle in the right placed for this. Also, there are lots of sharp edges that just lign up with your knees - lots of bruises to prove this. Another problem is the helper handle in the position where this fits in the nice case that's provided, is in the exactly wrong place to use it. And it is not simple to move it. So if you use it a lot, you end up not putting it back in the case. The chisel did have a corner chip off too right away. One more thing on the ergonomics - the cooling air inlet sits right where you naturally want to rest your leg against, which of course then blocks the cooling air. Again - poor design. Just making the cooling slots curve around the edge to let in air even if you rest against that part would have been a simple design improvement. But the "engineers" who work over there don't understand how things actually work.... After saying all that, would I buy it again? Probably. It has worked well and busted up a lot of 5-6 inch concrete for me (though it was admittedly somewhat green). No leaks yet. No screws falling out. As long as you know the ergonomics are rough, and the wattage is not as advertised, you can decide from there.
