I'm very satisfied about YAMM. Customer service is also very fast and helpful (I experience a couple of minor issues not depending upon YAMM). Great value for money!

I received a personal response to my request even though it was after hours (on a Friday). My request was completed by Monday morning with a personal note that it had been completed and also confirmed my subscription payment.
