FSA 45 is rated 2.8 out of 5 by 34.
Rated 1 out of 5 by from This product has advertised great features but does not deliver! I will be returning this trimmer tomorrow. I have a small yard and had to restring it 8 times when half done, so gave up on that. Bought larger diameter string but it snapped off after two feet. The centripital force causes the slot to act as a razor and slices the plastic string off. Then tried the plastic blades provided. Machine would shut off after 2-3- feet. Not a good investment and a surprisingly poor STIHL prodeuct. Extremely disappointed!

Rated 4 out of 5 by from The product works very well, but the battery could use a little more longevity I have a simple yard with two walkways, and about 6 bushes to trim around. The big thing is driveway edging. My driveway is about 125 feet long (250 total), and I can't do trimming and edging on one battery charge. This might be unfair because the "average" driveway isn't than long, and for those, the battery would probably make it just fine. And, it gets through all but the last 50 feet. The product is light weight, and does a good job. Overall, I'm very happy; I just need to know that I'll have to charge it again if I do both wacking and edging on the same day. No big deal.

Rated 1 out of 5 by from Long charging time for little use I could not be more dissatisfied with the Stihl FSA 45 trimmer. It takes 3 1/2 hours for a full charge which only lasts 20 minutes. If it is not allowed to cool down before beginning the charge, red indicator lights come on. I was under the impression that Stihl products were of good quality, but sadly this is not the case with this trimmer.

Rated 5 out of 5 by from I found my trimmer Recently I suffered a stroke. The person I once was is no more. I no longer have the strength to carry a large trimmer for a long period of time. I even bought an electric trimmer to see if I could handle it. I would have to pull out 150' of power cords and after trimming. I would be exhausted. One day, I noticed my neighbor with a battery powered trimmer and he just zipped around trimming his grass. Luckily Stihl was selling the FSA 45 at what I considered a price. I bought it and tried it out. Now I just have light grass to trim around bushes and sidewalks, but it has answered my prayers. It is light, and can use poly blades or trimmer string, but I have been using the poly blades and they have done the job. It's easy to use, again light to carry and I don't have to lug all that cord out each time I trim. I have used it throughout the summer and can't find fault with it. For light trimming this is the real thing.

Rated 5 out of 5 by from My wife wanted one for her. Birthday to help me keep up with the trimming around our place. She loves it, the light weight and quiet running. We have had the trimmer for three weeks but cannot find anyone that carries the replacement blades. The dealer where we bought it keeps promising they should be in next week, but not yet. Also it looks like the blades are quite pricey. So be sure to consider the aftermarket cost and hassle when buying.

Rated 4 out of 5 by from My 6 year old LOVES it!! The FSA 45 was a replacement for my 6 year old son's 20v Black & Decker weed trimmer. He absolutely loves the features of his new Stihl trimmer, a Stihl man through and through! After he proved to me how to safely operate a battery trimmer along with understanding basic operations and maintenance of his previous trimmer would I consider upgrading his tool to something a little nicer. As his parent I really appreciate Stihl engineering a "key" that can be taken out of the trimmer to prevent my son from accidentally endangering himself or someone else when I'm not around to supervise him. The run time is decent on the 18v as long you don't go crazy trying to cut over-growth or something. The trimmer is feature rich with extra plastic blades attached to the bottom side of the trimmer, ability to convert to edger, adjustable shaft, and adjustable head makes for a very ergonomic trimmer. I myself have the 36v straight shaft trimmer, 36v blower, and 36v hedge trimmer. Great tools Stihl!!
