Worth the Mon6
Other than a few mnior leaks at connection points! This sprayer is the best ive ever owned! Normally! It 45mins to hour to spray my weeds? I got it it done in less than 15mins! Over the past 5yrs! I’ve purchased 6 or 8 different sprayers that never even last 2 months? This is new! But I’ll know by winter? If it was worth the cost? So far! Very satisfied for the cost!

Great product, sprays like a pro.
Worked great, battery was fully charged so went right to work! 4 gallons on my back is a fair amount of weight, but it works and sprays nicely. Easy to operate, powerful spray. I was so tired of the hand pumps, and this is so much better!

Flawless So Far Plus a Pro Tip
I’ve only had the sprayer for a little over a month but I’m loving it so far. I have a large property that requires continuous herbicide spraying througout the growing season. I will never go back to a pump sprayer. I’ve run over 30 gallons through it and the battery still shows a full charge. Zero issues and I can be sure it will last at least 3 years because I bought the 3 year warranty. Pro tip: a number of reviewers have noted it is hard to sling up on your back. Set it on a table or tailgate.

Man this sprayer is a great buy. Does everything them big name expensive sprayers do and is 1/3 of the price. That thing will throw some liquid if you want it to,has plenty of power, and a lot of different attachments for whatever the circumstances that are at hand.
