I ordered the wrist strap in July this year. After I had now four weeks while in the US, I can only say: top product. I have a Canon 1000D, and just with the 55-250mm lens I had without the loop relatively quickly a cramp in his hand, because the camera just became front heavy. A wrist strap I could Camera also by 3 hours at a time in your hand (or loose on the wrist strap dangle) and still had no complaints.
The only slight negative point for me: The backup tape is sometimes a bit loose and sometimes slips out of its holder. This can be simple but with a needle and a short length of thread fix. A star deduction gibts so anyway because the manufacturers would do the same thing can (even fold the end over it with the sewing machine and finished ...)
Otherwise: class product, well worth the money in any case
