Review (5/5): love it!!!!
I have to admit, I was a bit skeptical about these tiny, battery operated trimmers. I know several barbers who swear by them. I saw them for 20 bucks on amazon, so I figured I'd give them a shot. While the blade is not designed to be adjusted, I managed to zero gap them. I've been cutting for about 15 years and I'm a master at adjusting blades. So it can be done, if you know what your doing. You can also put the T-wide blade, which is adjustable, on the G-Whiz.
I love this product. They are powerful and very sharp, but what I love the most is the design. It's small size and cordless feature makes for great handling, maneuvering and control.
