Rated 1 out of 5 by from Sprayers are not worth the money I purchased the predecessor to this sprayer and I was only able to use it for 18 months and about 25 gallons of product before the pump failed. Of course, the 12 month warranty had expired. There are too many parts that are made of plastic. I do not believe that sprayers are Stihl strengths. They do not last as well as chain saws, string trimmers and so forth. I would carefully evaluate product designs before purchasing a sprayer.

Rated 4 out of 5 by from Love the dependability of the sprayer First one used used it 2 years no problems. Still in use. Then I bought another one ( lots too spray ) have had it about 2 years, and bouth are in good shape. Ordered a 3 rd on to day ,so I’ll have 3 all in good working order. Tried other sprayers none compared too the STIHL SG 20 sprayers,And I use them a lot put hundreds of gallons through each one of them. I will never buy any other brand.

Rated 3 out of 5 by from $80 in repairs in 7 months and still has a leaky handle! Title says it all. Replaced handle and tip. Replaced gasket in top of the piston. Still has a leaky handle. I don’t know if I’m going to fix it. Definitely not the dependable product I expected from Stihl. I bought this sprayer new 8/21/17.

Rated 3 out of 5 by from Time to redesign stihl It’s time to redesign this sprayer stihl! It’s a piece of junk I’m constantly replacing parts on it I have broken the pump handle and had to replace almost every o ring on it. This sprayer is very heavy when it’s on your back I would really like to see more comfort added like better pads I am still thinking about buying some br 600 pads and fitting them on.... I’m a huge stihl fan but I think this is one tool most landscapers use on a daily basis and we would l8ke to see a better product!! Can’t wait to see what y’all come up with

Rated 1 out of 5 by from Not the quality that usually comes with Stihl name........ watch out for the cheap plastic parts that the handle and nozzle are made of. I have had a little less than a year and the handle assembly has completely broken apart?

Rated 3 out of 5 by from To many cheap plastic parts. Spraying wand is made of cheap plastic and therefore not very durable. Otherwise sprayer is ok and much easier to use than traditional garden sprayers.

Rated 1 out of 5 by from Disappointed with this sprayer After only minimal use the wand connection failed and it has to be tinkered with over and over so that all the liquid doesn’t just run down my pants. I have now resorted to holding constant pressure on it with my left hand and spraying with my right. Super aggravating.Usually you get what you pay for. This sprayer isn’t the case. On top of that the local dealer seems to think it must be a problem with me.

Rated 5 out of 5 by from Longest lasting in the market I couldn't disagree more with these sprayers reviews. We have over 60 of the sprayers some of them are several years old and still going. It takes a little bit of working knowledge in maintenance but they will last and last
