Top Amazon Reviews


  • Honest paid customer review - Not Amazon Vine
Not a “Paid to give 5 star” or “Amazon Vine” reviewer. I bought this from my own hard cash by looking at similar products sold by this company. Overall the sprayer is excellent. The best part about it is the battery - it is a long lasting replaceable battery. The second best is the sprayer and the large capacity. Plus it is comfortable to carry after filling it up. I’m not the most fit person by far and I went through 2 refills and 3 sprays and it felt very comfortable. Lastly the controls are reachable including the turn on/ off switch and the spray speed while on the back. Overall an excellent product. Highly recommend. ... show more

  • Works great!
For sprayers it works great! We have a little over an acre and though we had to refill it several times, we got the job done. It's super heavy when full so I'll post a pic of how my husband and I handled the task. Next time, I'll be sure to bring a wine cooler along lol.

  • Great sprayer
This sprayer worked much better than I expected. I put a mix of 3 gallons of weed killer and this made the job very easy. Tried a few of the tips and settled in the one with more of a concentrated spray. I can see using the fan tip also along my fence line. Battery did not even drop one bar.

  • Makes a very tedious project fun!
Fits very comfortably on my back, I pad my shoulders for more comfort. Made the spraying project much less onerous with the power. Able to efficiently do a larger area.

  • Worth a try
This is my review for VAXMAY Backpack Sprayer 4.2 Gallon Battery Powered, 100 PSI Electric Garden Sprayer Works with Makita 18V Battery, Weed Lawn Yard Sprayer with 42" Telescopic Wand, 5 Nozzles, 2.5Ah Battery & Charger from the VAXMAY Store. After a number of years toting 35 pounds of herbicide around plus 6 pounds for my backpack manual pump sprayer, I decided to get a battery powered one. I am now toting 43 pounds, but not pumping. This sprayer weighs 8 pounds. It's still a load but easier and quicker. This is a nice sprayer with some weak points. Unpacking the sprayer, my first concern was leaks since I'm working with herbicides. Top down, the filling cap was installed, but the cap gasket was not inserted correctly in the cap. I did not physically look at the hose at the connection to the pump, because it is behind a panel, so I was going to do a water test later anyway. The hose connection to the sprayer handle was loose, I checked the gasket and tightened that up. I tried the trigger lock. It fell off the handle immediately. Snapped it back on. I don't use that so no biggie. The rest of the connections on the wand needed tightening. It is 42 inches long if you want so the spray is away from your feet with no bending. The only spray head I use is the fan head. There was no indication of water flow on it. I substituted my old one which fit nicely. I put a gallon of water in it to test for leaks. Perfect no leaks. The water tank has very poor water level indicators molded into it so I made sharpie marks on it for every gallon I filled. The shoulder straps are comphy but I would have liked a center strap to hold the straps together. My old sprayer has this and it makes a difference. The sprayer pumps a lot. It would be very easy to over apply your spray. I played around with water, adjusting the pressure knob so I wouldn't kill my lawn when applying weed killer. The battery is a 21 volt and the Makita or generic are 18 volt. I don't use Makita tools so I don't know how the lower voltage effects spray time or performance if you change batteries. I applied several tanks and the battery indicator went down 1 volt! Not having to pump makes this chore a lot easier. I'm also happy I didn't kill my grass. Overall I think this is a good product with some shortcomings. The price drop from what I paid, now makes this a decent option and worth a try. ... show more
