Balancer question

Cool idea, poor execution.
As far as imported junk...
20 purchased over 4 years between me and the business I used to work with for various makes. 7 by me personally for my builds. 2 of mine failed due to outer ring slippage. Still have one on the shelf in the box. These failed but didn't destroy anything. Others all in service working fine by all accounts.
This is not the same brand that failed and wiped a crank that cost me $1500 last year. just my opinion here... which has changed over the last year... Buy an SFI one if you feel you have to use product from these companies.
