Rated 1 out of 5 by from Disappointed Just bought new stihl71 backpack sprayer and am very disappointed with it, you need to redesign this product and quit using plastic fittings. Go back to the old sprayers, never had the problems with it that I’m having now. Can I expect my money back and do you have a decent product that I can purchase? Do you make a adjustable nozzle for this?

Rated 2 out of 5 by from SG 20 I have mine for a couple of years and the plastic part of the end of the hose broke that connects to the wand and now I can't find a replacement part .

Rated 1 out of 5 by from Unreliable We own probably 60 pieces of Stihl now and have liked most of it. Bought a few of these and thought I’d get one extra for my house. Might’ve made it through two tanks of glyphosate and it won’t work. Guys had complained about the pumps. Prob should’ve listened to them. Take it to dealer to replace my personal brand new one and no dice. Don’t buy one of these. Stihl makes some great products but this isn’t one of them.

Rated 1 out of 5 by from this product is not good for regular use The nut on the end of the wand that connects the wand and hose to the tank is cheap plastic and continues to crack.

Rated 3 out of 5 by from Not traditional Stihl quality. Was very impressed with the sprayer the first season. Second season the sprayer handle started leaking and replaced the Orings. Slowed the leak until the hose started to leak. I did not use any type of solvent that would accelerate wear or deterioration of the rubber parts. Cleaned every time after usage and allowed to dry before placing the tank lid on the tank. Seems all sprayers have problems with leaks of some type and Sthil is no exception. I really like the unit except for the leaks that cause a big mess and makes the unit dangerous to use depending on the chemical being dispensed.

Rated 5 out of 5 by from Completely Satisfied with Performance and Quality I have several sprayers from 1 gallon to 40 gallon capacity for different applications and spray types. The SG20 has become my favorite sprayer for general exterior manual foliage spraying due to the ease of carrying the loaded sprayer, excellent spray pressure for coverage, and the ease of pumping while spraying. It's well designed, comfortable on my back, and easy to clean and maintain. I read a lot of positive reviews and also some negative reviews regarding the wand and other plastic parts being weak before I bought it. I found very little merit in the negative reviews when I inspected the sprayer before buying it. Anything can be broken by abuse or misuse and the .0001% defective part may get used but I have concluded that users who follow the recommended pre-use maintenance checks and oiling should have a good experience with it. I have had no issues whatsoever and expect many years of service from the SG20. The SG20 is one fantastic sprayer for the price.

Rated 1 out of 5 by from Absolutely Worthless I have bought five SG 20 sprayers. Four of them does not work. The most recently was purchased two weeks ago. It has only had basic Roundup run through it and already stopped working.The pump locked up on a sprayer only a few months old. All these sprayers have been cleaned daily and serviced. One sprayer the bolts that hold the tank on the frame fell out and the sprayer fell off in the highway. I am a licensed landscape contractor and purchased these items only based on the quality of other Stihl items that I own. This item is absolute junk. The biggest disappointment however is the poor customer service that I received from the people at Stihl,s technical support. I would rate this product no stars if possible.

Rated 1 out of 5 by from Broke after one season Worked great last summer and went to use this spring bam pump is all locked up. All this thing has to do is hold liquid, pump and spray. Dang it! Great used it 2x and now the tool that was supposed to save me time needs to get repaired.
