HA! So the Discovery Channel can beat the Germ Terminator any day with its 20 dollar toothbrush UV/Ozone germ killer. Small, compact, no idea how durable it is. I'll say that there are still some unmatched features of the GT such as dependability (heating elements don't break like UV lamp bulbs can) and absolute sterilization, but hey, it's 20 dollars.
Unfortunately, because 20 dollars and the need for future replacements still prices me out of absolute oral health, I won't be getting this device.
