| Locking Device
Hi guys
I've been really impressed with the results obtained from wearing my extender over the last 5 months. 3 weeks ago I added another 1" in the length of the rods but noticed that the comfort strip started to slip quite regularly.
I know that this may be because I've been trying to exert too much pressure, but I found the solution to the strip becoming loose was to use a plastic locking device found on the side of most scuba masks (the strapping on a scuba mask is similar to the comfort strip in most respects).
Anyway, it works for me! Hope this tip might help |
