I bought this clipper about a year ago, thinking it was just the thing for my short-cropped hair. I gladly paid the hefty (2X) price premium over conventional clippers. It is easier to use than the straight-bladed clipper it replaced, and I got through my weekly haircut in half the time. I congratulated the manufacturer on their creative design. Thank you, Remington! But within months the battery lost its ability to keep a charge, and now can barely run 5 minutes even when freshly charged. And Remington installed an interlock so you can't operate the clipper while it's being charged. I am an engineer, and to me this design has planned obsolescence written all over it. My guess is that they know that the battery will not last long, and want to push you into buying a replacement clipper. And since they apparently have an exclusive product, they figure that would be another of the same. Well, no thank you, Remington. I tolerate planned obsolescence in an average-priced product, but not one for which I paid a premium. Those I expect to last longer than a few months. And I'm just irritated enough by this to avoid following their playbook. So forgive my geekiness, but my next move will be to open the clipper’s lid and find a way to override the charging interlock, and maybe replace the battery while I’m at it. This was not my first Remington product, but will likely be my last.
