Ive got Mach 3 and Venus, I bought the venus when it was on cheap and I needed one for a weekend break.
Its good that I can buy just one set of blades but other half uses all of them and forgets to say when last one has gone so luckily I then have my venus blades and he has to buy the mach 3s again lol
Like many men when I was married, one of only a few rows we ever had was her constantly using my razors and shaving foam. She had these little double bladed pink things that wouldn't shave a peach.
I use the 'el-cheapest' men's razors I can find - usually Tesco's Value ones!
I do have a ladies wet and dry electric shaver but it is abolute rubbish - just doesn't work except to give my skin a rash - unlike the cheapo ones which are great!
