Review title is Poorly Designed Heads Fill Up Fast [SEP] The biggest problem with this design is that if you have a heavy/fast growing beard is that you may have to stop and clean it mid-shave. There just isn't any room for cut whiskers in the tiny heads and where a heavy 1-day growth is a maybe a 2-day growth is way more than it can hold. I think that may be why some people complain about the closeness and/or speed of the shave. It works really great until it loads up with fur and there is no room left for more. This is really a razor for those that have a light growth or shave twice a day cleaning it thoroughly each time.<br /><br />Note to Norelco: Increase the cut whisker capacity in next year's model.
