Rated 1 out of 5 by Not Impressed I bought this hedge trimmer along with a leaf blower and a weed trimmer in the spring of this year. The blower and weed trimmer have operated flawlessly but this hedge trimmer has been hard to start since day 1. Im very disappointed in this trimmer. I was expecting a very reliable piece of equipment and I never know if its going to start or not. September 26, 2016
Rated 5 out of 5 by Great trimmer for demanding use I have quite much hedges to trim, around my house and also at my mother in law's place. Mostly high hedges, wide, old grumpy branches but also some young and delicate sections. With the previous corded trimmer the hedge trimming was a ardouos weekend project... slow not only because of the cord but also due to lack of power.Since I got the HS45 some years ago the work is finished within an hour per site! Sure, the machine is heavier than a typical corded trimmer but the efficiency is in another league. The long blade cuts like a laser sword, really powerful engine that makes the work quick and fun! I would not say "effortless" because it is still hard work - and you need to have a rather strong back and shoulders to control the machine - but it is also a matter of getting the technique right, work around its gravitational center as often as possible. My wife says I look like Edward Scissorhands when I'm in action... the hedges are trimmed at an incredible pace yet with super precision!I find the HS45 easy to start, there is a special sequence you follow and it has never failed om me (the procedure is actually presented on Youtube for this and similar machines). I use alkylate petrol premix for my small handheld machines, burns much cleaner and is better for the machine and the operator. The machine has required no maintenance so far more than cleaning/lubricating the blade, an occasional air filter cleaning just as precaution. Maybe there is more that should be done but it still feels like new so why bother.There is only one thing that could be better in my opinion: vibration levels. This is not a machine for professional work during extended periods, I would say one tank or an hour is max for a work session before the tingling buzzing sensation in the fingers become a real concern. It is a hedge trimmer for occasional hard use a couple of times per year. September 20, 2016

Rated 2 out of 5 by Starting Issues If you can get this product started, it is a good hedge trimmer that cuts well. Unfortunately, it is very difficult to start -- I have had to take it back to the dealer twice -- before ever being able to use it. It also floods very easily. I would never have purchased this if I had know it was this difficult to start. Stihl must have know this was an issue because they have since improved the starters on some of the new products.

Rated 5 out of 5 by This hedge trimmer is almost indestructible As novices to working with outdoor machinery, we bought this hedge trimmer 2 years ago and it serves as an all round workhorse, once started it can take an absolute battering with no fuss whatsoever. It goes above and beyond the call of duty on every occasion, it has never broken down, created unconvincing noises or needed any parts replaced during its life (we have serviced it once as part of company scheduled maintenance and is due to be serviced again soon) but I'm pretty sure I could throw this thing in a swamp, pull it out 2 weeks later and I wouldn't be surprised if it still worked. It cuts through material of diameter I really shouldn't put it through, it has tackled many hedge/garden clearance task. I have complete confidence in the machine. September 7, 2016
Rated 1 out of 5 by If it doesn't start at the dealer easily, ask for another one. I have use the trimmer less than a dozen times since I purchased. Partly because the hedge no longer grows like it used to but mostly because the trimmer is so hard to start.Average start time seems to be around 15 minutes and because of the lousy pull handle on the rope you end up with a blisters on your fingers.

Rated 5 out of 5 by Great Hedge Trimmer I purchased this hedge trimmer to ease my task of trimming all the bushes on my 3 acre yard. What would have taken me several hours was cut down (pun intended) to just over an hour. These trimmers are easy to start, have plenty of power, and are easy to handle. If you have used any of the other Stihl products, this one will be a breeze to operate and maintain. August 9, 2016
