First I add my keys to my wallet. So having something strong to attach to is the first prerequisite. It is replacing a Swiss Army type whose zipper was failing.  That lasted a good 10 to 12 years.  I doubt I will get the same life, but if I do this will be a steal since this is about a third cheaper.  Personally I don't need as many card slots or the snap change or key pouch.  Those features make it a little thicker than probably most zipper wallets.  All these are not really negatives for me.  I am not sure how to verify if the RFID really works.

In summary. it is exactly what I wanted in terms of its core functionality.  The actual fit and finish is above average but bear in mind it costs $20 so it doesn't look and feel like a Tumi or Coach accessory.
