One spring has already disappeared from a blade when cleaning so down to 4 blades within only a few uses.
This shaver only works on hair with no more than a few days growth! My girlfriends ladyshave works better!
It's not something that I use daily and I'm sure if I did it would be great, it just doesn't suit me.
I find it a little flimsy and fiddly to take blades apart to brush out hair. Hence a spring popping out into the bin without being noticed.
