Does anyone have any feedback/experience with the Katadyn's Micropur MP1 water purification tablets?

Katadyn's states that this is a "chlorine dioxide..easy to use water purification tablet that is safer than iodine or chlorine. Infact, it is the only technology currently registered by the EPA that controls cryptosporidium, a waterborne cyst."

Thanks,
