    Work's and fit's. on back well

    I only gave the sprayer 4 stars because it leaked when i filled it up. Ended up having to tighten pump assembly clamp very tight to stop the dripping. Worked great after that and sets on you back very comfortable. Will see how it does over time.

  • Most critical review

    Leaks badly ... Lid will not seal ... chemical drips on my back when I use it ... terrible product

    I will not recommend you buy this ... everything works ... yet, lid opening is oval ... lid is round ... lid cannot seal and without seeping fluid when it is manufactured this way ... chemical leaks out onto the ground and grass as you walk ... it slopps everywhere you don't want it to !! ... chemicals leak over one's back and this is a health hazzard ! ... Quality control for SOLO is sub-standard ... hope you have better experience than me ... I was scammed !!!

  • Great Sprayer

    I had used a solo for many years but the last one had a pumping problem after about 5 years of use. I have roses and use a sprayer many times a month, I ordered a Chapin and it worked well for a while but after about 6 months it was hard to pump and spray. I took it apart and it worked better and the in another 4-5 months, it vapored locked and two hands could not get it to pump. I was back to the solo. Delivery was good and I am so pleased with the sprayer. No leaking and once you pump, it will spray for awhile before needing more pumping and the adjustable nozzle is very nice. I will stick with this brand.

  • Disappointing Initial Quality

    Solo sprayers have always meant high quality to me. However, after this purchase, the initial quality of the product had issues: 1) it leaked, 2) hose clamp was plastic and stripped under little pressure, 3) one of the holding straps was installed backwards. The leak was due not because of the hose clamp, but the bottom 'O' clamp holding the pressure tank was barely holding the unit together.

  • Good sprayer

    This is a really well made sprayer. If I had not owned one in the past, I wouldn't know the difference but the spray wand trigger is not as well made as it used to be. However, this is a well built sprayer.

  • Great Product for a Good Value

    I have used several brands of back pack sprayers, but have not found one that provides the dependability and quality that Solo provides for the price. I like the spray pattern that the nozzle provides and the ease of controlling the pressure with the wand. The only negative is that the back of the sprayer could provide some padding for comfort especially when the sprayer is full, but is only a minor inconvenience.

  • Good product, good deal

    My second Solo sprayer. First one lasted 20+ years. Zorro tools was an excellent source. The sprayer was well priced and it arrived THE NEXT DAY.

  • Average product

    Was a little disappointed because my older solo sprayers hand could food up next to the tank this one lays down. It's not landscaper friendly like my old one
