Rated 4 out of 5 by from Starts easy I really like these trimmers. The only thing wrong with mine is every now and then I feel something binding up. Not sure what it is but, it does not stay around long enough for me to pinpoint where the issue is. But other than that it's my second purchase of this product. I got 4 Years of use, with one that I bought at a pawn shop. With buying this one new I'm looking for 6 to 8 years!

Rated 4 out of 5 by from Stihl products are solid tools. The hedger been hard to start since I purchased it. Once it does start, it has to run a little bit before it can be turned at an angle.

Rated 5 out of 5 by from Best product for the quality and fits our needs. We bought the HS 45 to replace a pair of Stihl gas trimmers we had been using for over 23 years. Knew the product was worth the money. Never spent money on repair of the trimmers. Excellent product. We knew we wanted a Stihl product as our replacement. No complaints for having to buy a new pair based on the years service we got out of the old pair.

Rated 3 out of 5 by from This product is hard to start The dealer had issues trying to start the new hedge trimmer. I thought it was just him, so I took it home and had the same issue; when the unit is cold or hot. Also, it seams to act like it’s going to bog out under normal operating conditions. Going to take it back to the dealer. Overall, As a Person that only runs Stihl products, I am very disappointed in the performance of this tool.

Rated 5 out of 5 by from Upgrade from electric Bought this trimmer on sale and it has been excellent. Starts easily, runs strongly. Far better performance and freedom of movement than electric. A slightly longer cutting bar would be the only improvement.
