Query: Poor design

I have used Norelco shavers for many years and was happy with them. This design, however, is poorly developed. The three heads have small individual compartments for cut hair and must be cleaned out daily. It's clumsy to open them and the razor is nosier because the heads are above the casing. Also, the charging stand uses up counter space.
