Racquets Rackets

I restrung two racquets with the recommended string from the shop's owner (Gamma Revelation, total paid $60.00), I played just two weekends and both strings resulted in terrible choices, I only played at most 6 hours total, my forehand is very weak, so there is no explanation for the bad quality of the Gamma Strings. I'm very dissapointed, almost angry.
Good service, bad string quality and bad recommendation from the shop's owner (he mentioned to me that the strings will not brake that easily). Gamma Revelation = BAD, BAD
