Rated 1 out of 5 by from This sprayer is TRASH!!!!! Ok I get it there are far more expensive sprayers and you get what you pay for , Got it . Well check it out I have the more expensive ones and I bought this for bleach and bug spray , light stuff around the farm. It is JUNK , I have used it maybe 3 times and it now the wand part of this junk sprayer has small holes so whatever I have it in sprays out when pressure is in the tank. This is the first review I have ever had anything to do with, I had to pass this on . It is junk do not buy it . And if you do buy it Do Not put bleach in it , it well spray all over your clothes and ruin them too.
