VIVOSUN 1.59-Gallon Pump Pressure Sprayer, Pressurized Lawn & Garden Water Spray Bottle with Adjustable Shoulder Strap, for Plants Spraying, Garden Watering and Household Cleaning

Arrived on time with very clear instructions. I use this to maintain 100+ houseplants, and it works exactly as needed, very effective. The attachments switch out easily, it holds pressure well, and I’ve had zero leaks. The adjustable shoulder strap makes it comfortable to carry, even when full. Great quality and very practical—highly recommend for plant care or light household use. Great quality for the money!

This is the best sprayer I've ever used, and I absolutely LOVE it. I purchased it in June 2019, and it worked really well until after I'd estimate maybe a couple of dozen uses, at which point a leak developed in the base when it's pressurized. It seemed to be at those points where the black base attaches to the orange body of the sprayer, on the bottom. I used Goop glue on all the possibilities for the leak, as it wasn't obvious just exactly where it was leaking. Unfortunately, when I pressurized it the next time apparently the glue didn't hold, and the leak is even worse. I'm giving it 5 stars because it's such a great sprayer, and I suspect this leak was a fluke, just a glitch in manufacturing, but I'll have to buy another one. Meanwhile, I'm using an old Green Thumb sprayer in its stead.

First the pressure release valve breaks. You then replace it. Then the pump loses pressure as the seals in the mechanism no longer fit tightly. I bought three or four of these and had to throw away two of them. Finally learned my lesson and will stop buying these units. They seem well made but in truth just junk. Howver, customer service is very good and offered me a full refund.

We use this to clean our dirt go kart tires works great.

Bought this last year and the first time I used it, worked great. Second time, the upper funnel part where you pour liquid in, kept releasing air while pumping it up. Had to use every bit of strength that I have to tighten this part down to finally get it to where it would not leak air and lose pressure. Then the third time, pumped it up and noticed when I used it that the manually adjusted sprayer nozzle had changed its pattern of spray without me changing it, but basically thought it was still usable. Then, when I went back to use it again, I noticed that there was a huge puddle, as it had leaked all over the place from the bottom. I noticed that many other reviewers have stated that there was a leak from the bottom as well. I think this is a design flaw and maybe that's the reason for the extra black sleeve attached to the bottom? I originally thought, from the heaviness and what appeared to be the sturdiness of the sprayer, that it was a quality item, but I was wrong. I think if it's going to split at the seam on the bottom from possibly too much pressure, as I can think of no other reason, then there ought to be a pressure limit with a pressure gauge indicator for reference. Spilling/leaking dangerous, toxic and poisonous chemicals all over is a very dangerous situation. I consider this a total waste of money, unsafe and am currently looking for a replacement and have no idea what to purchase as I don't want to get burned again!!! Extremely disappointed!

This design is good in that small debris can not get into pump area and unseat the flapper valve that holds the pressure in and so it does not leak solution or pressure. It does have a pressure relief valve to be used when done as desired.

Very good quality. Works better than the store bought ones.

Worked great for 5 months then started leaking air like crazy.
