Anyone use or ever use the shock blocker 500 stabilizer from NAP? just bought one because my old one broke and it looked pretty good, plus it was the cheapest one they had[8D]

I have a shock blocker 1000 on my ar34 ram cam and a half. I can tell a difference with mine when i shoot and a little on the vibration side not much. I notice i do shoot better with it on and i was told it would reduce string slap which i dont know bout that. My bow doesnt have much vibration and i imagine with your matthews you have the same as mine or prob less. For the money i think its worth it. I may hop mine up next year to see if i can tell a bigger difference. So far im happy with mine.
