Rated 1 out of 5 by from Disapointing Always been pleased with what I’ve purchased at Tractor Supply but sadly, not with this sprayer After just 2 usages, the sprayer wand cracked and vegetation killer got all over my arm, hand, leg and foot.

Rated 1 out of 5 by from Wish I would have bought a different sprayer. Purchased it at the end of last season and used it twice. Cleaned it out and stored it. Just got it out today and on the second pump it stopped pumping. Now, according to the other reviews I'm not alone. I waited to write my review til I could get an idea of the quality and now I can tell you to stay away from this sprayer.
