The Robbys Cool Max and the Brunswick Air Commmand are virtually identical, while the Command X is extended length.
I find the support on the palm side obnoxious and pull it out, or at least straighten it a bit. The support on the other side works well. Either one can be bent to suit your hand better, too. For my personal preference I pull them both out and use the rest of the support to keep my wrist warm, and restrict movement just a bit.
As far as durability you should probably get a couple seasons from one unless you take it off all the time for spares (then the velcro will wear out first). They are a very cost effective option in my opinion.
