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

Rated 1 out of 5 by from Not a good product. From day one the unit leaked at the fitting where the wand connects to the sprayer. After a few weeks the plastic fitting failed. The location I purchased the unit from at 1st did not want to warranty the part and wanted to charge for parts and labor to replace the wand fitting. I treat ponds as part of my business, of the several sprayers we own this was the most expensive and has given me the most trouble. I have many Stihl products, most of which are awesome. This sprayer is not.

Rated 3 out of 5 by from Won't hold consistent pressure and wand leaks a lot. I received this sprayer as a gift this spring. It either sprays real hard when full then really weak after use with constant spraying. The wand leaks a lot from the end and appears to be poorly made.

Rated 3 out of 5 by from Disappointed I've had my sprayer for about three years, and I've had issues with the pump a few times, had to lubricate it a few times, replace one seal. I have had a cheap plastic one from the local box box the whole time too with no issues.

Rated 1 out of 5 by from Poor design and results in leaks I have three of the sprayers. Like others I thought that this sprayer was the typical Stihl quality. I was wrong. I had to replace the wand handle twice on one sprayer. The second and third also leaked at the wand and a couple of other points. The poor design causes the sprayer liquid to cover my hand and arm. I am very disappointed with Sthil selling this type of design. This sprayer does not warrant the Stihl name. By the way, I own backpack blowers, cultivator, line grass cutter/weeder, three chain saw, powered pole pruner, hedger, etc. ALL Stihl and all of high quality.

Rated 1 out of 5 by from Love Sthil but do not recommend this sprayer I'm a big Stihl fan and use all Stihl equipment for my lawn care business. However, this sprayer was a big disappointment. The build and quality seem to be great but I've had trouble with it ever since I bought it and, unlike most Stihl products, the dealer told me it didn't come with a warranty. The pressure never regulated like it's supposed to, spray blasts out when it's fully pressurized and then the stream gets weak. After about two months of use, I had to continually pump to keep the stream going. I've checked all of the connections, gaskets, etc. and can't seem to figure out the issue. Stick with Stihl for power equipment but I do not recommend this product.

Rated 5 out of 5 by from Just what I expected Many of my customers have been asking me to spray for weeds this year. What better time to pick up a sprayer. I researched other brands on the "top 10" weed sprayers on many different web sites but in the end I thought I would just go with the brand I trust. I was not disappointed. Ease of use and quality construction are two of its many fine points. It actually makes spraying for weeds fun and quick.

Rated 2 out of 5 by from Too much Maintenance, failure Every other year i need to replace parts in the pump canister. A very common problem is the threaded rod strips out the nylon threaded washer . Needs replaced with mini use.
