fulfills the purpose 11

This bottle I've been more than a year in use and it is still suitable. Although the thread can slightly and is determined to break even, but in plastic, nothing is to be expected otherwise. In the winter I have wrapped in bubble wrap, that the water does not freeze. Up to -10 degrees has worked great when it got colder, I had in the morning and evening replace the water that I gave me a second bottle concerned. To clean I (not the plastic !!) immersed for 10 seconds in boiling water the metal funnel. Many drops she does and the metal bracket for attaching also sufficient. You could use a second wire around the bottle to fix down something if the cage leaves too much room and can slip the bottle back and forth. But on the whole, it served its purpose and my two dwarf rabbits use without problems.
