Much Better Than Earlier Model
I replaced my T770 model after the battery died for good.  The T770 did a fair job of trimming and a terrible job of collecting the hair via the vacuum missing a good 30% of the hair.<br />This model is much better at the main job which is trimming the beard.  It is very precise and trims the hair effortlessly.<br />The vacuum feature is improved and only misses about 10% of the hair now. However, it seems that if you are going to have to clean up any hair why bother with a vacuum feature at all.  Cleaning up is cleaning up. It makes little difference cleaning up a little or a lot hair.
