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!!

Rated 1 out of 5 by from Suitable for a child's toy Blades wear out in ten minutes. Bogs down in thin grass, then you have to press three, yes, three, switches to restart. I am sorry that I bought product.

Rated 1 out of 5 by from NO REPLACEMENT BLADES = USELESS My first Stihl purchase. Bought mainly on company's reputation. It was what I was looking for, a trimmer with blades instead of line. I've always had bad luck with the spools of tangled line from line trimmers, so I bought the FSA 45 Trimmer. Worked fine, not terribly powerful but I bought it for smaller jobs and went into it knowing what I was getting. What I didn't know was that I wouldn't be able to get replacement blades. They are non-existent as far as I can tell. I've checked at all of the hardware stores and online, read reviews and for some reason they can't be found which basically means I bought an expensive disposable trimmer. As the weeds grow I must now go out and purchase another trimmer. Can you guess what brand it won't be?

Rated 5 out of 5 by from Lightweight, low maintenance trimmer for yard work I bought this trimmer from my local full service dealer and love it. I don't have a huge amount of property to cover so except for the first use when I started getting the yard into shape I've been able to do clearing and edging for both yards on one charge. This trimmer is very lightweight and easy to use for basic yard duty. The only problems I have with it are that the blade coasts rather than braking when the trigger is released, and the fact that the blades seem to wear fairly quickly. Fortunately they are relatively cheap and extremely easy to replace, and I have learned how to use the trimmer better without wearing them down as fast. Overall I would recommend this trimmer for basic yard maintenance with little to no hassle or maintenance required.

Rated 4 out of 5 by from I like this FSA 45 After reading all the negative reviews, it makes me wonder if people were expecting more out of this little yard trimmer. And... I love the string option. Yes people it has a string option of .065 right next to the blade attachment. Either your dealer is not informed or you didn't look at the manual. I traded my Ryobi 20volt rig for this one and I am happy. Next time do some research on the tool your buying. Don't buy a claw hammer to drive railroad spikes.

Rated 1 out of 5 by from only thing i like is its lightweight I am so disappointed! Always heard Stihl was the best I beg to differ. For the money I paid 2 months ago only to have it back at the dealer twice. They wont refund or exchange. When the Red lights come in its an Electrical Malfunction. Or so the manuel says. I had only used 7 times when the lights came on took to dealer they RAN it 3 times no problems after keeping it almost a week. I found out today they didnt Use it. Because after using 3 more times it started with the Red lights again so I was back at the dealer. Apparently its ok to use something with an Electrical Malfunction! Also the line will not stay in. It flies across the yard so therefore you have to buy the more expensive blades which get chewd up around fence or concrete. Also theyvhave to be kept in water to keep from breaking off which I was not told. I could go on and on but I have to go try this thing again.

Rated 1 out of 5 by from Greatly disappointed in this trimmer Purchased this product for my wife. She does most of the trimming, she's small, so small and lighter weight were a priority. Purchased at a dedicated outdoor equipment dealer, so we would trust their judgement a bit more. To say the least, both the decision to purchase this model, and the information given to us before the purchase, have left us greatly displeased. First, we were told by the salesman that recharge time was in the half hour range. WRONG. Multiple hours needed to fully recharge. Second, the blade life is terrible. The blades are not breaking, they are just flat out wearing out in a very short amount of cutting. It came with extra blades, she's went through those in very short time span. Before purchasing, we asked about the option of converting to a string type head. We were told that using string ran the battery down much quicker. With the short life we're already experiencing, I can only imagine how little could/would be done if we converted.
