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

Rated 4 out of 5 by from Good, not great... Now that I have ran a half dozen+ tanks full, I have a learned opinion. Overall, it's fairly robust. The pump arm is sturdy, along with the tank. The spray wand feels slightly flimsy, but it hasn't been a problem. So far the biggest oversight is in the fact that the wand doesn't have lock-out feature. I feel this is a substantial problem, as when you need to move from one location to another, it's not always practical to relieve pressure from the system. On two occasions the wand lever bumped into something while loading the pack into a vehicle, and in spite of trying to be careful. This resulted in spray on my pants leg and a bit on the trunk liner of my vehicle. I plan on making a lock-out block myself, but this is something that should have been incorporated from the start.As for carrying comfort, it's better than a Solo, but still wears on you once you start that third tank full and beyond. The nozzle spray pattern is consistent, and the filter in the grip has not plugged up the way the Solo filter in the tip often does. Overall I like it, but really would like to see a lock-out feature on the spray wand.
