I havent had a chance to use the balancer yet but the product arrived very fast and was exactly the way it was described.

I first used the Buzz Master in school to statically balance props and found it simple and easy to use. Actually, I found it a little too sensitive in the beginning but became more adapted at using it the more props I balanced. I now use the Buzz Master as a part of my prop balancing service. If the ips readings from my dynamic prop balance set are to too high to start with, I know I will need to begin the process by using the Buzz Master to statically balance the prop. An economical, simple but sensitive tool.

Good concept, But cheaply made -- String breaks with the slightest weight on the buzz master. Must be restrung through the slug--not an easy fix !

Im sorry to have to write this,... I was looking forward to getting My Prop balanced as soon as I could,... first of all, I have a rather Lite Prop ( Powerfin) ... and when I suspended it from the Buzz Balancer,... about a Minute of hanging the string broke,... so I tied it back,... and tried it again... about 3 mins later it broke again...Probably a weak string on this unit...??? I wasnt Mad or anything,... I heard You would make it right... but I just thought Let the buyer beware ... No hard feelings...
