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.

Rated 5 out of 5 by from Great Product I have been in the pest control industry for nearly 20 years. I have owned my own business for 15 of the 20. This, by far, is the best bang for the buck. We have bought 10 of these over the years, all of which are still in use. In reading the reviews of previous owners, it seems that these people leaving reviews think since its made by Stihl it's made out of steel. You can't expect to drop any sprayer and not have a crack. As I tell my technicians, you need to be careful with the wand because it is made out of plastic. This is a great product, if you treat it with care.

Rated 1 out of 5 by from Looks good but... I've had this sprayer for a couple years. The main issue I had from the start was the harness straps...they are not easy to adjust and dig into your shoulders when you have a full tank. I replaced the wand once when the full tank fell over and accidentally broke it; the plastic wand is the most fragile part. Recently, the seal where the pressure module enters the tank started to leak and this has become problematic. Also, the rubber hoses have a short life span; mine have already begun to crack and leak...I would not buy this model again unless certain improvements were made, I'd be willing to pay extra for a more durable product.

Rated 3 out of 5 by from Great features Amazing products that stihl has in production bit I will say the straps that go over your shoulders are so un comfortable. I would like to see the straps off the bg 600 or 700 on these sprayers.

Rated 1 out of 5 by from Only two months old and having problems I bought the sprayer at the end of March. I've already had to replace the wand because it wouldn't shut off. Now it won't build up pressure when I try to pump it up. I went with a Stihl sprayer because I thought it would last longer than the cheaper sprayers I've been buying. Looks like I was wrong. At least with the cheaper ones I could get through a mowing season. I like it when it was working properly but not very happy at this point.

Rated 2 out of 5 by from Don't recommend I have owned this sprayer for under a year and I was moving it around this winter and dropped the wand on the ground from a few feet, just the wand bot the whole thing. Well the wand snapped in half and parts are not even available. The pump also locked up on me
