Now to the HC5780:
The hair trimmer fits comfortably in your hand, is not too heavy and the handling is super. It is nice that you can adjust the cutting length in the operation, but this can not happen by accident due to the lock. The gradation (here in 3mm increments) could be a bit finer.
The battery really lasts a long time by, the engine develops a lot of power and can be - if you want - to operate at two speeds. So overall a great hair clipper when the essays were not so soft. At the big top, this is less of a problem, but the little essay this becomes noticeable. To shave eg 3mm, pushing a little too much, so the crests of the essay diverge so the blade then comes much closer to the skin. This has resulted in some fast lines drawn by the beard. So here caution. Otherwise, I can the trimmer now absolutely recommend About 6 weeks use, I hope I do not like to correct some point down the HC5950 this information.
