  • Good 👍
Light weight making it easy to use, easy to ensemble, spray works great, good pressure.

  • Was a Good Sprayer but….
Great sprayer. Works as described. My only complaint is the straps. They slide onto the bottom of the unit (they don’t clip in) so often when trying to put the unit on your back the straps come loose. The head seems to leak as well. Other than that it has worked well. UPDATE: It’s now March 15, 2026. I’ve use the sprayer 3 total times. I went to use it today and the handle has a pin hole in it so it’s sprayer weed killer all over the place. I would expect this after just three total uses. ... show more

  • Great seller!
Worked well until pump failed after using several times—and after the return period expired. The seller was very prompt to evaluate and respond. Sent a replacement sprayer. Will buy from this seller again!

  • Poor
Not performing as it described

  • Spraying Power not as great as advertised
Spraying Power not as great as advertised and mixing takes longer then putting your chemicals and shaking up the whole container; that being said it's a good sprayer for the money and if you live in one of those cookie cutter homes then this is a good solution for doing your yard etc..

  • Almost good..
Tank works just fine, I like the circulation pump feature. The hose and handle are junk, leaks all over. I replaced the hose and handle after my first use.
