Rated 2 out of 5 by from Underperforming for my needs. I was looking for a battery powered trimmer to store at my camp and decided to try the FSA 45. I thought it would be nice to not worry about transporting fuel every time I went to camp. Being a Stihl, I was confident that I'd be happy with this trimmer so without hesitation I bought it and off to camp I went. I performed a full charge and started my trimming endeavors but was quickly disappointed. The trimmer just didn't have the power I was expecting. It would be trimming and just shut off once I hit a thick patch of grass. Getting it started is a chore because of all the switches and triggers on the handle have to be repressed. I was doing mostly continuous trimming and after about 20 minutes the battery was dead and needed recharged. Also, the plastic blades didn't cut as well as I was hoping they would. The tips wore away very quickly which decreased the cutting radius in turn increased my cutting time. The edging option was nice but it also wore the blades down even faster. The blades are cheap to purchase but you'll need to stock up on them. I would really recommend this trimmer if you have a very small area to trim. The trimmer is very lite weight and easy to store away because it is retractable. And I'm sure it will last along time because Stihl just doesn't make junk. For me, I just had to high of expectations for this trimmer and I bought the wrong one for the job. I'll be returning this for a gas trimmer. I'll probably just buy the Stihl fuel and store it at the camp because it has a two year shelf life.

Rated 1 out of 5 by from Do NOT buy this product Based on a recommendation from the Saw / Rental Shop that I buy equipment from, I purchased this unit on March 30, 2017 for my wife to use.in her garden.I tried to order extra polymer plastic blades for this unit at the time of purchase and was told "They are easy to get." BAH - HUMBUG!!!!!!It is now May 21, 2017 (6 weeks later) and the replacement blades (which are poorly made) have been back ordered by the STIHL Company time & time again - I am unable to use this piece of junk because the STIHL Company does not back-up their tools with adequate replacement parts or competent service. DO NOT BUY ANY OF THESE RECHARGEABLE BATTERY TRIMMERS!!!!t if you do,.......... "You'll be SORRY!!!!A VERY, VERY Dissatisfied Customer

Rated 5 out of 5 by from Great product if used for its intended use. I am surprised by some of the negative reviews. The product is small, light weight, intended for small yards, and quick jobs. The blades are poly blades that are solid and which are great for grass and other small weeds. Fences, concrete, rocks, and other solid objects will greatly decrease the life of the blades, however there is a metal guard on the front that you can put down to make sure you do not cut too close to such objects. I have a small 5000 sq ft. yard, I trim by lots of fence and flower beds using the guard and the first set of blades have lasted more than a month. The unit comes with 8 blades and I am still on the first set. It is different than a string trimmer and should be used accordingly. The battery life isn't incredible but again is more than sufficient when used accordingly. If you have a large yard or are planning on clearing large square foot areas, than this product is probably not for you. Again if you have a larger yard get a larger, more powerful, higher capacity battery setup, which Stihl also has.

Rated 1 out of 5 by from DO NO BUY! I have been buying Stihl gas products (trimmer, blower and hedge trimmer) for over 30 years. They are remarkable and require little maintenance. I gave that equipment to my son before moving to a community where lawn care was provided. I decided to invest in the battery powered trimmer after realizing the lawn crew was taking nicks out of the concrete around the edge of the house. Be warned, the plastic blades did far more damage in one day than the lawn crew did in a year! Since this model cannot be adapted to a string trimmer, I will look for a Stihl string trimmer. Dissaponted!

Rated 1 out of 5 by from Beware of blades The blades for this product last for one use, and are relatively expensive. The trimmer line option involves very thin line which only lasts about three or four linear feet of trimming. Upset that I wasted my money. Definitely need to consider models that have more traditional line and feed features in the trimmer head.
