Solo backpack a winner
The Solo 425 Deluxe is a great performing sprayer. Glad I got the deluxe model as it has a pressure gauge, a brass nozzle, and padded shoulder straps. I use it for herbicides and it reaches far enough to spray blackberries with enough volume that I otherwise could not reach with my old small hand-pump sprayer. The hand pump works really well and is easy to operate without taking the backback off. Obviously it is heavy when filled to capacity, so I only put 2 gallons in which lasts a long time. Finally, the Solo is easy to clean. Great tool!

Good unit overall, used to spray 18 acres
I use this sprayer to keep my dog runs free of fleas and ticks on an 18-acre property. I am spraying about 2 acres. Generally, it takes 2-3 refills to cover that much territory. I would rate the product an additional star if the straps were better padded and the unit was easier to lift over my shoulders (the straps tend to be hard to adjust and therefore hard to get on). The sprayer itself does a very nice job, and I had no issues with the adjustable nozzle. No parts have come off or needed to be tightened in a few months of use.

Not worth the money
Backpack accessory is very uncomfortable-won’t stay in place. Wand for sprayer and pump handle are not good quality. I am 3 days too late to return it otherwise it would be going back. Not worth the $188 investment

Read a lot of reviews before choosing
Very happy with this unit which I've used a number of times now. I like the large capacity. The harness is acceptable to me although could use a cross strap on the front so it doesn't slide off the shoulder. The piston pump works extremely well and it is easy to maintain pressure with my left hand while spraying with my right (also reversible). Several pressure settings with a nice gage on the nozzle head. Durably constructed overall, a very nice quality unit... Good job Solo!

Solo sprayer
I bought a used like new sprayer, the box it was delivered in was the original box, but not taped closed. I am missing the spray nozzles and the bolt and nut that are used to install the handle. Should have purchased new

Great sprayer if you plan to use for stronger weed chemicals, it will hold up over time. Owned this sprayer for 2 seasons and its doing very well, just be sure you tighten your bolts as i had one fall off and needed to find a replacement. Only other issue is if you fill up the sprayer full, it can get uncomfortable on the shoulders as the padding is not as thick as it could be.

Bought it before the season started, leaking when I got it but stopped after a few fills. After 3 months of use cannot get any pressure have to buy a repair kit. On top of the price of a repair kit I have to buy another sprayer to get me through the wait. For the price not worth it, the cheap ones last me 1 to 2 seasons .
