I purchased one through chinworld.com
LOVE IT!!!! my chew-monster can't get to it!
It hangs on the outside with a protective metal panel between the exterior bars and the bottle itself. The panel is sold separately.
It doesn't drip, even in the car b/c it is different than a ball-bearing bottle....diswasher safe, easy top loading lid. I love it! might have to train your chilla to it... pat on it, get water on finger, put near her mouth, repeat. Mine got the idea w/in 2 days.
Haven't seen it for lower price (only $13 total for both bottle and sheild), but you can always search on google, or the google for products, froogle.
FeaturesFlip-top opening for easy filling on cage.
Positive closing Edstrom Valve elimanates drips.
Edstrom Valve has very low actuation force...easily operated.
Edstrom Valve does NOT operate on vacuum principal...therefore saliva and feed are not sucked up into the water bottle.
Rectangular shaped bottle mounts neatly to side of cage with stainless steel mounting spring.
Lid can be removed for easy cleaning of bottle.
Edstrom Drinking Valve is constructed of brass and stainless steel with rugged silicone seals.
Water stays clean and fresh.
Dishwasher safe.
