The product has a piece of hard plastic blocking the end of the strap which can twist. Totally useless and fake. This is the second time (first time from this seller). I had this problem when I bought this strap from Revain - just take the hit in your wallet and order the strap from the Garmin website. UPDATE: The seller was very responsive and fixed the issue. I missed something - this item is perfect! If you complain that this item does not fit, do not completely remove the old belt.
