Info on this water gel/beads?

[Presideo]

Anybody know how long to keep a pillow in a humi? Many places say that they are supposed to be tossed after a single stint in a travel humi, but does anybody have a time-table for how long a single one will last?

Keep reusing it until it fails. I have some gel jars in my cooler, the same stuff in the pillows, and they say there are good for a couple of months or one recharge.

I've recharged them literally dozens of times and they are at least 2 1/2 years old.
