I have the Remington had now about two years, may be disposed, since he no longer works him now. Reason is the very labile touch unit and the rapid discharge of the cells. These were after about a year - about three times per week in use - emptied. Now held a charge only for a half (!) Section. The touch control functions with regard to the length setting is no longer, the unit remains in an undefined state stuck, can neither turn in nor out, is no longer functional. A renewal of the batteries is not possible because the unit has no screws for their disassembly. By Vorgängermodll - without touch control - I had the same experience in terms of fast battery drain. For me, not a Remington model more out of the question, I am now switched to Philips with lithium batteries, curious if the holding better.
