Review (4/5): Fantastic Trimmer
I bought this trimmer because of it's built in guard and vacuum capabilities. I've been using it about once a week for the past 4-5 months and have been extremely satisfied so far. It does not catch or pull while trimming and I've had no difficulties with the guard slipping to a lower setting as others have reported.
The vacuum works great catching most of the trimmings. It does leave a few trimmings on the sink but those are few enough to simply rinse down the drain with no worries.
