Well, as a owner for a few days, I have to say both positive and negative things.

The positives:
* Strong motor
* Quality hard plastic (construction)
* Titanium head (Cuts excellently)
* Battery still hasn't died on me, I've done over 5 haircuts and it's at 23%
* Doesn't get clogged with black dog hair at all!

The negatives:
I expected more extra combs, especially 1m and 2m.
* Takes 2.5 hours to charge (I wanted faster charging)
(For the price, it's excellent)

4 stars for what reason?
The reason is that while you're cutting someone's hair, with one wrong move, you can cut them live! You have to be careful.
Good line from this company, but there are specific parts that have come out with better quality in another set I bought and turned out useless the next day.
So be careful!
