Most: - Good cut, no need to insist; - Cutting Guides "Locked" (so far it's effective, I hope that with time and wear of plastic parts, it will be the same); - Good battery life; - Very good grip.
Cons: - Not a lot of accessories (eg no guide to the outline of ears, no beard size); - No charge level indicator (LED just when to recharge the unit).
Overall I am very satisfied with this purchase: the price / quality ratio is very good.
