I ordered this Croakie and a Chums Slip Fit (http://www.amazon.com/gp/product/B003CJWI9C/ref=oh_details_o02_s00_i01) spectacles retainer.  I had no experience with either brand and did not want to purchase an off-brand; I wanted high quality and reliability.

Of the two, I immediately found the Chums to be the better product FOR ME and the Croakie not to my liking at all.  The problem I had with the Croakie was the fabric.  Since it slips over the ends of the temple pieces and envelops them, the fabric sits on one's ear.  I found this irritating.  The fabric is soft and a bit "fuzzy".  Holding it in one's had is pleasant, but for me sitting on my ears was not!

Some may not find this an issue.  If that is the case, then the Croakie is a good choice as it is well made, grips tightly and the length should be good for most people.
