Review: Reliable - Works well. I have used Solo backpack sprayers for many years on the farm. A reason to buy Solo brand is being able to replace parts that do wear out. I bought a Tractor Supply 'some other brand' one time, and couldn't find exactly the parts needed to repair the unit (diaphragm, gaskets), so I had poor results and had to discard it. Solo puts more design efforts into ergonomics, too.

great backpack sprayer. love that the spray handle is on a swivle. allows for easy transport and storage. no longer have the pump handle in the way

### ⭐ Decent sprayer but mine had a defect that SOLO refused to fix.
*by H***N on May 21, 2025*

Arrived with a hole in the tank where the tank is blow molded around the metal frame. Liquid from the tank drains into the metal frame. This caused rust to form in the inside of the frame, which causes rust to back flow into the tank when filling it. This is obviously a manufacturer’s, but I have contacted Solo for a warranty claim and they have ignored me. Outside of that it is an ok sprayer but kind of poorly designed. The way the shoulder straps attach to the frame is ridiculous and is not secure. I ended up having to zip tie the strap attachment to the frame so they wouldn’t pop off while in use. The chest strap is so bad that I just removed it after the first use. The brass nozzle is all but useless. The plastic nozzle works fine though. It does spray bleach without issue, so that’s nice?
