I bought this for my husband because his keychain was overstuffed, and I wanted him to have something with easy access to keys and other things (whenever he flies, he has to take off his Swiss Army knife). This key ring looks great and seems to be of quality construction. I like that it can hold several keys and accessories.
While I like the screw-on/off ball at the end so he can switch things in and out without prying open a traditional key ring, I offer one caution: make sure you tighten the ball very well. The day after he got it, we were walking out of a restaurant, and I saw his pocket knife drop to the ground, then found that other things had fallen off because the ball wasn't properly secured. Fortunately, we found everything, and he has since tightened it up and not had further problems.
One thing I would like to see offered for this product is a choice of fonts on the personalization - the script is more feminine than I'd like for my husband.
