Rated 1 out of 5 by from I will not buy another Stilh productions I purchased this weed eater because of it name and price It was a mistake, never again . I brought it home and barely got it started and got the job done. The next time I could not get it started so I took it back to the store. Thy got it started and told me it was flooded. So I took it home and it would not start again by now I was disgusted with this item and got out the electric eater . I have on several occasions tried to start this machine with no luck. It was cheep but it doesn't work, lesson learned. Junk!

Rated 1 out of 5 by from Hard to start, hard to keep running and line feed does not work My previous trimmer was reliable and easy to use but was poorly constructed so I was excited to get one that had more solid construction. Unfortunately that is only good thing I can say about this unit. To preface, I am an engineer and I know how to use a 2-cycle engine and I use the proper pre-mixed fuel. The trimmer just doesn't want to start. I actually don't trim very often since its only about every third time that I can actually get it started. Then it seems to take a few minutes to warm before I can actually trim with it. And if that isn't bad enough, I can only get about 20' of trimming done before I have to manually feed line out (and start it again). The line feed feature of tapping it simply does not work. In fact I usually have to completely unscrew it and manually pull it out. I don't have a large yard... it only takes me about 35 minutes to mow. It usually takes me about 25 minutes to trim with trying to start and having to feed line out.

Rated 4 out of 5 by from Product performs as advertised Quality for the price. A straight shaft is better but more expensive.

Rated 1 out of 5 by from Poor quality product Bought this FS38 trimmer from Ace Hardware three weeks ago. Extremely hard to start the first time (and yes I read the manual) and also had to stop the trimmer six times to release string because tap and go feature did not work Ace Hardqare would not take back this product after only four days. Decided to give it another try. Restrung the spool line myself but have yet to be able st start the trimmer. Definitely would not recommend.

Rated 5 out of 5 by from I love it! I've had my Stihl FS38 trimmer one year now and I love it! It's easy to start when I follow the steps. I'm 5' 2" and it works great for me. It's a real work horse compared to other trimmers I've had. I would definitely recommend it!
