As you you see in my pictures, my sporasub blade had broken from the same places on same week. I have used them tops 30-35 times total. I have actually contacted the Italy where their HQ are, they had directed me to Turkish distributor. Unfortunately Mares, the Turkish distributor of Sporasub, has not been helpful and they simply not doing anything about it. It is very frustrating to see a very nice product in the hands of very unprofessional people. Even if they decided to send a new pair of blade, I am sure that it would be broken from the same places.
