18V ONE+ 1 Gallon Chemical Sprayer is rated 4.7 out of 5 by 261.
Rated 5 out of 5 by from Easy set up, lightweight, and good to go! I just used this for the first time today and I love the design and ease of use. In the past I've always been frustrated with hand pumping sprayers and this one makes spraying those nasty weeds a breeze!

Rated 4 out of 5 by from 18V ONE+ Gallon Chemical Sprayer I bought the unit at the end of last season, 2021. The unit worked great and is easy to operate. However, I cleaned and emptied the unit at the end of last season and just recently I pulled the unit out to spray some areas and found the main body of the sprayer, between the trigger and the nozzle has a seam that has a seal and it's leaking, which now has a mist that comes out the side. The unit will already need replaced, hopefully it will be covered by warranty.

Rated 5 out of 5 by from Great sprayer Love this sprayer wish I had years ago. I’m in my mid sixties and can look back now at all the headache it could of saved me from ease of carrying, ease of filling and emptying, trying to pressure seal tank when pumping and especially no pumping!

Rated 4 out of 5 by from Worked good I used it to spray a sealant over my pavers, but beware do not let it sit without using all of the sealant. You will have to clean it out if you let sealant sit. So be sure to use it all at once.

Rated 5 out of 5 by from great sprayer This sprayer worked beatifully. I used it to apply weed killer before we planted the garden. Love the metal sprayer wand. I used a black marker to highlight the level indicators on the bottle.
