Rated 5 out of 5 by from Best Stihl trimmer I have used Extremely powerful for thick stuff with the brush knife, great for trimming as well. I only use Stihl for my small landscaping business. Starts easier than any other trimmer I have used.

Rated 5 out of 5 by from Excellent and versatile. Great local dealer I already have a Stihl chainsaw and leaf blower. This trimmer was a replacement for an old non Stihl trimmer. I bought it 3 weeks ago and so far it has exceeded my expectations.

Rated 5 out of 5 by from Excellent Trimmer As always another great product from stihl. In my line of work if your equipment doesn't work your not making money, that's why I only use Stihl. Everyone needs to understand anything will break if not properly taken care of. All my equipment is cleaned and checked after each use. As long as you take care of your equipment it will take care of you when you need it

Rated 5 out of 5 by from Haven't owned it long, but I'm very happy with the trimmer. Outstanding performance. Nothing to add. It performs as you expect.Works far better than this site which apparently requires a book for a review. I said it works and it does.

Rated 5 out of 5 by from FS 90R This is my third FS 90R. They are great products. The first 1 I had I was using and slipped while cutting bank on canal. It was running and when I slipped I dropped it in canal. It was running when it went under water. I retrieved it. I took it straight to my truck. I emptied gas tank, removed air filter, removed spark plug. I took my blower and dried everything out. I put new fuel in it and replaced the air filter. After doing this it cranked up and I used it another 5 years with out any problems. I highly recommend this product. I personally would not use anything else.
