Rated 1 out of 5 by Is this a Stihl??? I've had this HS 45 for 3 years - I was able to start it twice. It's disgusting. I own the Chainsaw and the weed wacker. Both start flawlessly. April 13, 2014
Rated 5 out of 5 by Product has great safety features The trimmer is light weight and very easy to use, the safety features require the use of both hands for operation. This is a very good safety feature. March 9, 2014
Rated 2 out of 5 by Difficult to start and keep running I bought this unit a number of years ago and have had problems with it almost from the beginning. It is very difficult to start and keep running--it dies as soon as load is applied. I have had it serviced several times by my local Stihl dealer without any improvement in performance. I am disappointed in Stihl--my Stihl chainsaw is one of my most reliable tools. February 27, 2014
Rated 5 out of 5 by Outstanding tool After using an electric hedge trimmer for years, I decided to break-down and purchase a gas unit for around the house. Glad I did and very happy that we purchased the HS 45 because it is a real work-horse for any and all hedge trimming we have around the home. I must admit I was taken aback by its sheer power and ease of use. It is very easy to start and maintain. I absolutely love it and would highly recommend it to anyone who has hedges that need an occasional trim. January 17, 2014
Rated 5 out of 5 by HS 45 with 24inch blades If ever there was a great hedge trimmer, it bleeds orange and grey! This HS 45 has power and fast trimming ability on even on thick branches! I decided to get the 24 inch blades for off property jobs and it was well worth it. Unfortunately, there are some drawbacks: During the beginning of the season, it does take a good amount of pulling to start it up, but I found that the MotoMix helps cut that away. The engine is a little loud, but the Stihl ear protection equipment takes care of that right away. The fuel tank is very small but refueling is a snap. Finally, the unit does get a little heavy if you haven't used it in awhile. ;) All in all this hedge trimmer is well worth your money and most importantly, your time! December 9, 2013
Rated 2 out of 5 by Can't keep running I love styhl products and have had a chainsaw for over 21 years and have had great service from it with only minimum service trips but the HS45 trimmer is impossible to keep running. Yes, I drain the gas before storageand it's only a year old but it still will not run at full speed and dies when you start trimming...IE it's useless! October 26, 2013
Rated 5 out of 5 by The best machine that money can buy and worth every penny!! There is a saying that goes "you buy cheap and you will buy twice". This is true, when I first bought my home 5 years ago, my wife bought a cheap electric hedge trimmer. She used it a handful of times and it quickly started having problems such lack power, the plastic coverings were cracking and breaking at the handle, the electric plug base was getting loose and the extension cord would come out during trimming sessions just to name few. I picked up this STIHL model hedge trimmer and I immediately noticed the superior quality in design and performance. This trimmer is a beast and surprisingly very nimble and agile to handle and control. It's makes the harder jobs faster to get through without any problems. This device is lightweight, powerful, easy to handle and looks very sleek! Like I said before, money well spent! June 18, 2013
Rated 2 out of 5 by Difficult to keep running First I bleed orange and white owning 4 different Stihl products but the HS45 hedge trimmer is giving me fits to keep running. Not sure if this is a systemic problem with this unit or isolated but for sure one that should be researched before you buy. May 29, 2013
