Rated 1 out of 5 by from Surprisingly Unsatisfied Very excited to see the Stihl display at my local Ace Hardware. Had been looking for a cost effective, light weight, rechargeable blower for my property. Saw it & bought it, then found out I should have read the small print. Battery only had a 10 minute life span, so I returned it. You can't do much in 10 minutes. However, it was printed right on the box that it would only last 10 minutes, but I missed that in my excitement. Upon my return of the blower, I investigated other products in the display. Hedge trimmers with only a 7 minute battery time, etc. So Stihl, the store display is very attractive, the re-chargeable products look very attractive, but (unfortunately), you can't accomplish anything with such a short battery life. And yes, I inquired about getting a larger battery, but the one offered only adds 5 minutes to the life span. Sorry, but I was super disappointed.

Rated 2 out of 5 by from Minimal effectiveness Not much power for its size. Battery might last 5 to 8 minutes.Heavy spring on trigger with no lock to stay on. Cheap battery charger.Maybe ok for deck or garage clean up.

Rated 1 out of 5 by from This product is a total waste This product has about 8 min of use on a full charge. I own numerous Stihl products and have not been disappointed. This product is a total waste and disappointment.

Rated 2 out of 5 by from No battery life When I purchased this blower, I was told it was great for blowing off decks, driveways, and sidewalks. Sweet! This is what I wanted it for! I got my deck and half the driveway done and it died!! The battery only stays charged for maybe 15 minutes. This was not explained at purchase. Very dissapointed.

Rated 1 out of 5 by from Inferior My blower runs 5-8 minutes. Took it back to dealer and they said Stihl told them run time was 10 minutes, that I could pay the difference for an upgrade. This product is not worth the money. I would not recommend it. I will say that I have numerous other Stihl items that are great.

Rated 1 out of 5 by from very short run-time I have a 1500 sq. ft. driveway and with a full charge, this blower will not clean it when there is only a small amount of debris. Less than 20 mins. run-time.

Rated 5 out of 5 by from Super tool I bought this blower from a local distributor a couple of weeks ago, for my wife since she has trouble getting our heavy duty Stihl gas blower started being petite. It is great not only for her but i use it all the time for small jobs.After giving it a full charge, i found it worked for 15 min straight doing a gravel road at about 80 F today. interesting, it runs at full power all the way until it just stops. I didn't get a warning by it running sort of slow before it just stops! I am okay with that as long as i know it is going to stop after 15 minutes of continuous operation.
