Title: Doesn't cut very close - not recommended
Product review: I've owned the predecessor to this model, the 411, for several years and had great luck with it. It's getting old, so I upgraded to the 421, which is much quieter and cuts with ease. Unfortunately, the 421 is useless because it leaves a considerable length of hair behind. In fact, it leaves as much hair as I used to start with when trimming with the 411. The blade on the 421 is recessed from the tip way too far. I'm an engineer and studied the inside of the unit to make sure there wasn't a manufacturing defect, and everything looked very solid and well assembled. I cleaned up my old 411 and it's working far better than my new 421, which is headed for the trash or a return to Amazon. Definitely not recommended.
