Great Product
This is my second Norelco Vacuum Trimmer and as before, this one has been a fine product.  I have no problems with the guard slipping to shorter lengths.  I wear a medium length full beard and I use this trimmer to shape and trim.  The battery life is fantastic(four trims so far), the turbo mode works perfectly, and the vacuum is good.  It is not difficult to clean.<br /><br />The only issues I have had are the fact that this is not a duel voltage system and the design of the vacuum places the blades more towards the center of the head instead of right at the fromt.  With a bit of care the blade placement is easy to get used to.
