Ok so I have only had it a couple of years but my 177 has now settled down - VERY occasionally loosing the odd hair but how long can we really expect these brushes to last. My Father in Law still has an old 'Boots Special' that has been on the shelf for around 45 years. It looks like it has to go and looks VERY sad next to my baby but he will not part with it despite the fact that it looks more like the sad end of a well used and very small paintbrush!!! I only mention this as perhaps I can treble my shavemac's life on that which will undoubtedly see me to my grave and back a few times.
