After I’d been using this shaver for about a year the shaver head would separate from the shaver body during shaving; this became more frequent and irritating as weeks went by and made it impossible to shave without holding the head and body together! Under the terms of the Warranty Philips replaced this shaver with a similar model but the same thing happened after about a year in use. Initially I found this shaver difficult to hold without accidentally pressing the on/off switch but I found a way to grip it so that I wasn’t accidentally pressing the switch, but that wasn’t comfortable. I’ve stopped using this shaver model and wouldn’t recommend it to anyone.
