There are a lot of reviews out there saying it’s not worth it to buy these heated water bottles but I completely disagree! Living in Vermont we wake up every morning to our bunnies water bottles frozen and we have to go through the 20 minute process of defrosting them and refilling them just to do it all again when we get home from work. Having these heated water bottles have saved us so much time. We own three at this point and I highly recommend them to anyone living in frigid temperatures!

The lid is designed backwards, awkward to fill when installed on cage. Lid flanges too delicate, gotta be cautious not to break them off. My rabbits managed to remove a metal nipple making bottle unusable. The springs and clips holding the bottles to the cages are fiddly, if you clean bottles often, they will drive you nuts. Nozzles froze in negative temps, and last but not least, the wires at the base corroded heavily by six months use.
