Blimey, I didn't realise it was something people had strong opinions about.
For years I used Gillette 2 blade thingies but Boots stopped doing them and I ended up with some other thing, with about 17 blades or something, the refills for which cost a fortune. So expensive, that they are now locked to the shelf, making the process even more infuriating. Eventually I bought a load of 2 blade ones from Amazon for a suspiciously low price. They were shite, naturally. So now I had a box of hundreds of blunt blades. That was the tipping point. I got a Braun series 7. What a revelation. No more fecking little blades that don't fit. No more puzzling over the array of expensive tat in Boots. And another thing, have you noticed how narrow the aisles are in Boots? People are always trying to squeeze past while you're puzzling over whether you want a Gillette Badgernadger (£17 for three) or Wilkinson Stinker 29 (£46 ea). They can feck off now. Narrow-aisled bastards.
Hmmm. I seem to have strong opinions on the matter. I never realised.
I'd love to justify it on the grounds of single use plastic reduction but I doubt that the sums add up.
