Bests & Worsts Reviews from Amazon

I'm just a regular homeowner trying to keep my lawn (about 8K sq. ft.) green and weed free. Up until now, I have been using a hand-held sprayer that I purchased on Amazon. It has worked quite well. However, pumping consisted of taking the tank off my shoulder, pumping it up on the ground until it reached proper pressure, then putting it back on. Spray and repeat that every couple of minutes for an hour... It also came with a flimsy strap that cuts into your shoulder almost immediately. ENTER the Chapin Backpack sprayer! What a breeze this thing is compared to the hand-held. The back-pack style harness is a total back saver. I no longer get the customary back/neck/shoulder aches and pains trying to over compensate for a 3 gallon container on one shoulder. Also, the Chapin hand pump is almost effortless. It is way less laborious than my previous sprayer. Also, since you don't have to remove the pack, it has the advantage of being capable of continuous spray, as you add pressure while you dispense. The Chapin 61900 Backpack sprayer has turned the business of applying herbicides to my lawn from a chore into a reasonably therapeutic activity. PS - I have not experienced any leakage issues that I have read about in some of these other reviews. Although, admittedly, I do not expose mine to the same strenuous conditions as others probably do. Also, mine arrived with a nice scratch on the pressure gauge. I called Chapin, and they sent another one out immediately (no questions and free of charge). I had a whole new handle/gauge assembly within a matter of days. The company stands behind their product. Great (responsive) company and a great product!
