Guards pop off WAY too easily
Just received and haven't cut with them yet. The good...quiet, compact, feels solid, and the design seems like it will allow better angle to trim the back of head/neck area of my child (my primary reason to buy this - he is very squirmy).  The bad...plastic teeth? top part is metal, but moving teeth are white plastic.  We'll see how good they cut or last.  The biggest issue right now is the fact that the clipper guards pop off very easily with the slightest pressure upwards on the guard points.  I can envision many a 'oh-cr&p' in my future.
