Had the 1.0 it was great at first but it's nothing crazy compared to the 3.0. The trimmer is more light weight and the battery is quite fair. I think the ring light around the blade helps with that. A quality improvement. Let's not forget the eyebrow trimmer which is new. I do not personally use it but I love the ability at my disposal. A complaet upgrade. Very Satisfied.
The motor is slightly better than the 2.0 but is just as precise. The attachment is good for the tricky hairs closer to the surface and doesn't snag or catch and pull.
