    • Quality sprayer
After having this sprayer for going on 2 years I am very satisfied with it. Comfortable to wear and easy to pump as you go along and no issue's with it at all.If your considering buying one I don't believe you'll be disapointed

    • could not be happier
the only thing I regret about the Husqvarna sprayer is that I didn't buy one sooner. I have used it four times now, it works better than great, the back pack set up is perfect in that it feels great, offers great support and allows you to wear it with comfort. The sprayer is a joy with easy to pump, very good reach and an assortment of nozzles for spray density and volume. This sprayer is very well built, and a bargain for sure, you won't be disappointed ... show more

    • Get a tee jet nozzle. 4 gallon backpack sprayer.
The 2 included plastic nozzles are useless. Try them on dry concrete. Very uneven and worthless. The brass nozzle fine tuned should be good for spot spraying but a 1 gallon pump sprayer is far more useable for spot. With the included pressure regulator the tee jet course spray AI11004-VS red nozzle is excellent. Plug n play. Bought local at an ag store for $10.50. Tee jets are used in large farm sprayers and work great. Pros: Pretty well padded. Pumping is not too bad. Metal wand works well. Regulator works ok. Seems solid. Cons: Package wide open with tag open box. Amazon you really do suck at packaging and politics. Adding 1 tee jet would make usability 100% better. Pump handle bolts in for use position. Sticks out for storage. Unbolt for storage. Wrenches needed. Straps are not quick release for cleanup on bottom. Cleanup is a choir with multiple liquid sites. Using multiple chemicals is very risky because of near impossible complete flushing. Add roundup and it may be best to only ever use Roundup. With a good tee jet and single use chemical this is a solid sprayer for big jobs. For ease of cleanup and small jobs get a 1 gallon. Used for Prodiamine 65WDG(Barricade). Red tee jet high volume nozzle spreads even ~4 ft band. Yellow color residue stick to everything on sprayer. Overlap ~1.6 gallon H2O per 1000sqft. Fast spray ~0.6 gallon H2O per 1000sqft.. Spray with no sun and low wind to avoid using dyes. I did use a cheap HF 100 ft rope for large lawn area for boxing off areas with the slow overlap method. ... show more

    • Highly recommend
Perfect. Works flawlessly. Easy to use. No leaks. Will spray to a wasp nest on the gutter of a 3 story building. No kidding. Fabulous tool. One complaint is pump arm DOES NOT fold out of the way for storage unless you remove its mounting bolt... so arm is sticking out and continually in the way when sitting on the shelf of my workshop. Minor issue. PS To guy who says pump handle is unusable/ wrong position: Remove pump handle bolt, put handle in correct position, reinstall pump handle bolt. Problem solved. PLEASE don't ding people (companies) unless there actually IS a problem. Yes the instructions were vague but this is an excellent product.... best I have ever used in 45 years of doing this type of work, and the handle, once set up correctly works perfectly. I have used this thing for hours at a time with NO issues and it is easy to pump. ... show more

    • Best sprayer I have bought
I have bought several sprayers over the years from a small engine Echo to the cheap 3 gallon sprayers from the big box stores. If you have a large area to spray, this sprayer will do the job. It was extremely effective in spraying my moss covered roof with a killing solution and cleaner. It is relatively light weight for someone with a good back. I also saved on solution compared to my power Echo sprayer and the coverage was consistent. One drawback is that it is for close in applications. It would not be the best for spraying the topsides of larger trees. ... show more

    • The worst backpack sprayer
Where do I begin? Do I start with the fact that the packaging and description lied about the pump lever being on the RIGHT side of the unit and not the "left" side which it describes? I had to manually try and take off the bolt which ended up being difficult to remove AND to re-install to adjust the lever so its for left-hand pumping. Or do I start with the fact that it leaks? Or what about the fact that it has too many annoying straps? Or...maybe it's the fact that after 2ish weeks, it completely loses all of its pressure after two seconds of squeezing the sprayer, out of the box for like a week it was holding pressure just fine, now, it loses all pressure so fast it's literally the useless garbage I was using on what made me purchase this in the first place. I don't know if I got a complete dud, but this backpack is completely useless now after not even 3 weeks. I'm a pest control technician, this was the alternative to the Craftsman 4 gallon capacity sprayer for $199 at Lowes, this unit was not even $130 with the same capacity, and I was fine not having a battery and having to manually spray. DO NOT PURCHASE THIS BACKPACK. YOU WILL REGRET IT SO FAST. ... show more
