I saw other reviews that said that this trimmer was hard to handle and had awkward switches. The switches are awkward and would be better if you could lock the device in the on position but I imagine that it has to be the way it is for safety reasons. The trimmer is hard to handle when extended because of the weight of the cutting unit. The shoulder strap is good idea but did not help the problem in its original location. I moved it much closer to the cutting unit and actually wear it around my neck when I use the device. The unit works well otherwise and serves the purpose that I bought it for.
Do the job for my home works. I have doubt about its durability, will see in the future. It is seems made with a lot of plastic and maybe not too strong. It is heavy, but for a 30 minute job it is fine.
