FSA 45 is rated 2.9 out of 5 by 53.
Rated 4 out of 5 by from Heads up to shoppers While the Stihl website calls the FSA 45 a string trimmer it is not. Apparently it comes equipped with only the plastic blades that have been reviewed so negatively by previous reviewers.To get an actual string cordless trimmer, I opted for the FSA 56, about $70 more. Unlike the FSA 45, it does not have a built in charger. But it is still light weight with battery pack in place.I will comment further on the FSA 56 after I have used it for a while.

Rated 1 out of 5 by from Not happy The blades on this trimmer are crap. Can’t put a spool in. Not happy. Would not have purchased if I would have known how crappy the blades were. Have to loop string in if I want to use string.

Rated 2 out of 5 by from Blades are not durable Have only used product once. My yard is not large or extreme in edging requirements. The blades wear down WAY too fast. Edging usually means trimming close to fencing, concrete, etc...... and these blades are woefully inadequate for this purpose. Everything else could be perfect but if one critical component ‘fails’ routinely then the entire package is wasted. Make the blades longer and stronger....please.

Rated 4 out of 5 by from bad design It's a quality Stihl product. I love Stihl products but, this trimmer has blades instead of line for trimming. Just bought and don't want to use it anymore. They are very harsh. If i wanted harsh I would have bought a gas trimmer.

Rated 5 out of 5 by from Working well for me This works well for me, I can't start those gasoline trimmers, about a 20 minute charge is enough for my yard.

Rated 2 out of 5 by from Avg Homeowner??? I thought this would be all the trimmer I need for average Homeowner. Wrong, I get frustrated every time I use it. Charge does not last long enough to finish my lawn; edging sidewalks & trimming around landscape edging.The blades DO NOT LAST long enough. I go through approx. 4 sets a weekend. They are not cheap, either and hard to find. My Hardware store that sold me the trimmer, never has them and closest lawnmower shop is 5 miles away. Also, as they get close to the end, they the ends fall off in the lawn or sidewalk.I have purchased blades on-line, "made in china???" version and much cheaper, but do not last as long as the Stihl blades.

Rated 5 out of 5 by from Light in Weight yet Heavy Duty You won't need a back brace maneuvering this trimmer and your arms won't be fatigued either. Having over twenty years of Professional Landscaping experience, I've used more expensive trimmers that weighed more than twice again as much, and frankly string trimmers are a nightmare when then start going bad. The two blade system cleared undergrowth without a hitch and proved to be more durable than I imagined. The no-nonsense rapid charging was clear, concise, and the battery life when fully charged outlasted the project. You can buy less expensive trimmers and you'll be disappointed. You can spend even more and get a heavy gas powered unit that won't be as convenient or as easy to operate.

Rated 5 out of 5 by from Great Trimmer I know Stihl been around for a long time and have great types of equipment that meet the customers need. I have been using Black & Decker trimmer in the past and want to change it to a better one. I am staying with Stihl brand after I tried the trimmer twice and it was better than my old one.
