## Customer Reviews

### ⭐⭐⭐⭐⭐ It just works
*by A***H on July 17, 2020*

This was a lot cheaper then taking it to a small engine shop and have them tune it once I installed and new corroborator on my Stihl MS 460 chainsaw. Found the all the RMP settings for my saw online and it was easy. The one change I can think of is to make the clip for the spark plug wire a little smaller for the hard to reach plugs (like a chain saw) but I was able to use it no problem. Great product!

### ⭐⭐⭐⭐⭐ Great little tach
*by T***D on June 16, 2021*

I like this little tach. The clip is small enough to clamp onto small ignition wires in tight spots. Seems really accurate. Works great on 2 stroke & 4 stroke & different cylender configurations. Only thing I don't like is the battery isn't replaceable. At this price who cares....buy another one in a few years

### ⭐⭐⭐⭐ SEARON Digital Chainsaw Tachometer Tach Gauge
*by R***. on September 19, 2020*

I received this tachometer yesterday and took it out on my little boat today. I needed to measure the rpm of my Yamaha outboard to determine if my propeller selection was correct. This tachometer is easy to use and seems to be accurate. I did have to make an extension wire because the pick-up wire wasn't long enough for my application but that is not a complaint about the unit.However, I do have a complaint about the unit. The battery is not replaceable. Why in the heck would this company make a unit without the ability to replace the battery? I bought this unit because I did a search for the best portable tachometer and this one was on the top of the list. It does what it is supposed to do and functions properly so that is encouraging and I am aware that the expected battery life is 4-9 years. It's my fault for choosing this one but it is beyond me why a company would make a unit like this without making the battery replaceable. Really? How hard could that be or is it planned obsolescence (i.e., forcing the user to buy a replacement when the battery dies)? I do realize that the warranty is two years and I will certainly send it in for a refund if the battery dies before the two year mark.
