Review (1/5): Poor design, poor build quality
Having used several Norelco trimmers in the past I looked forward to using the top of the line T970. I am very disappointed after using it for six months. I have gone back to an earlier model while waiting for delivery of my Panasonic trimmer.
The vacuum works OK, it decreases the amount of clean up but certainly doesn't elminate it, but the real problem involves the regular use of the device. If you have a beard and a moustache a requirement for this kind of device is that it be able to trim at various lengths and then be able to have the length comb removeable. I found the pieces very hard to disassemble/reassemble for use. It would take many tries to get the thing back together.
Then pieces started falling off the unit. The mechanism that changes the length is needlessly complicated and fell apart. I found the use of the trimmer frustrating.
Overall this is about the poorest consumer electronic device I have ever owned. I have moved over to Panasonic trimmers since this experience was so frustrating.
