Summary: Iv'e known how to trim my own head for years. In the past my favorite tool was the Panasonic ER224 (also with one adjustable guard) until I broke the guard on it. That thing would hold a charge like nothing iv'e seen. Don't know yet how the philips clipper charge will do. This thing seems like a great hair trimmer so far (having one adjusting guard instead of a bunch to keep track of is the only way to go for me). Only one thing I would change on it to make it perfect.
Summary: One of the best features of these trimmers is all sizes in one guard. Over the years I have found the most annoying feature of hair clippers is all the gaurds to keep track of, whether the dog eats one, or you loose one, these trimmers bypass that problem. With a single adjustable guard you never risk loosing a guard because you don't need to change out gaurds for different lengths.
Pros: all sizes in one guard, cordless option, few parts, elegant design, rounded guards
Summary: I have just had my first hair-cut with this product, so I don't have a long range opinion. However, the hair clipper performed very well. Its easy to handle. Having just one attachment for cutting various lengths of hair offers convenience. The attachment is ultra-flexible an only time will tell how it will hold up. The initial charging was as implied; approximately 10 hours. Again, time will tell how long subsequent charges will take.
