First Shaver Won in get the first 100 free offer

When I won my first Azores razor free by entering a competition, the quality of the shave was great.
When purchasing replacement blades there the problem started poor quality shave.
I thought give it one more try big mistake, when one is paying around £7 for 4 replacement blades the quality should be good.
The blades will not stay in the razor, and this is common with the 3 razor units I have, apply any pressure and the blade unit falls out of the razor.
I have now returned to the cheap disposable razors which give me a good shave.
Azor King of Razors I think not.
