I got a hold of a bunch of 'Unit Pack' Dessicants made by Dessicare, Inc. They're about 3"x4" in size and packaged in what appears to be 'Tyvek'. It says on the outside,"Reactivation time in bag 16 hours at 245 F." That seems like a long time to reactivate such a small pack. Has anybody had any experience with this particular brand? Thanks a lot.
