  • Great sprayer
Style: Sprayer
I must buy two pump sprayers each season and none of the last past five or six uses. I have used this 4 times and each time refilled it twice. No issues so far. No leaks, pump works, no complaints at this time. Maybe finally found one that may last a bit.

  • No pressure; UPDATE 4/11/23
Style: Sprayer
UPDATE: Finally got a hold of customer service and the 2 guys in the technical department were very knowledgeable and very helpful-- they immediately sent me new part and it is fixed. SOLO has always been an icon in the backpack sprayer arena and their customer service shows this. Late review here... After only 3-4 uses (after 1-1/2 years), I have to continually pump to hold even moderate pressure. Not as good as the SOLO sprayers from years ago. I will be calling SOLO customer service next week. ... show more

  • I wanted a sprayer similar to what the pest control companies use and this sprayer meets my criteria
Style: Sprayer
I wanted a sprayer similar to what the pest control companies use, and this meets the criteria. It was easy to unpack and get started with. The pump arm works great. It is so nice to be able to pump a sprayer without having to put it on flat ground. And I do not have to pump it as much as one of those cheap sprayers that you carry and have to place on the ground to pump. I can keep my spray pattern consistent by quickly and easily doing one more pump using the arm, which really speeds up my work. Only time will tell how well it holds up, but so far I love it. Well worth the money. ... show more

The hose wasn't long enough on the spray wand, so I had to add some. Other than that, works great!

  • Good sprayer, even for this gal !!
Style: Sprayer
It works well, and I left off the 5th star only because the straps don't have a chest-level cross-latch. Some might find this picky, but when you have 4 gallons of chemicals on your back, that weight tends to pull the backpack off your shoulders. As a 5'3" tall woman with good upper body strength, it adds stress to my back. My solution was to hand-fashion a cross latch with Velcro and nylon strap. Problem solved Otherwise, It works like a charm. + I like the fact that the gallon measurements are in raised in the plastic itself. It won't wear off! + The pump is easy to work, and I find that as I walk & spray, its easy to keep the pressure for continuous spraying. + It has a nice screen / filter at the opening. Just unscrew the top, fill with chemical(s), replace the screen/ filter, fill it with water from the hose, and you're good-to-go. Sometimes there's debris in water lines, and the screen/filter is the same heavy duty material found in the backpack itself to prevent those particles entering your water reservoir and, subsequently, clog the tube system . + I really like the base, designed to keep it upright, even on uneven surfaces. Since I'm short, I can set it on a trash can, add chemicals and water, and just step into the straps and hoist it onto my shoulders, without stressing my back (by lifting it from the ground up to my shoulders). ... .The base keeps it steady, even when I'm not graceful in hoisting it onto my back! I've been using it for about 3 months now, and it's so easy, and I don't get tired (as I did with the smaller, hand held type sprayers), so I find I use it much more often, and the weeds don't get ahead of me. I would buy it again, for sure. Hope this helps --- Leslie in East Tennessee ... show more

  • Solo sprayer
Style: Sprayer
This sprayer came and I tried it with water as suggested, it was leaking from the sprayer connection with the tank, my husband tried to tighten it with no avail he had to change the clamp, it was only then it stopped leaking. On using the spray the weight of the sprayer and water/ weed killer is heavy and the straps are inadequate for the weight I had very sore shoulder after spraying. It is however nice to use. ... show more
