Pros: easy install
Cons: overflows with in a week
This is useless for chickens. The internal mechanism clogs within a week and causes the entire water container to leak out. There is no way to prevent or fix this because the valve is inside the molded together component.
I began to do a little research and found that everyone was having the same problem. After about a week, the float wouldn't shut off so it just kept running until the whole bucket of water drained out on the floor.
I had gotten mine from a different vendor and here is what they wrote to me about the problem:
"I am very sorry to hear of the trouble you have been having with the
mini cups. Yes, we are aware of its cons and what it is, if you were
to unscrew the base on the cup, there is a float inside that does not
hold its seal. After some use, which is what you have noticed, they
begin to retain water inside the float and that just causes it to run
all the time. There is no shut off from the float because its
flooded. So, I would be more than happy to refund your money for the
mini cups. We are waiting to get the improved version from our
manufacturer hopefully soon. I am told. I am not sure when but we
will announce on the website when they are here. Please let me know
what you would like to do. Thank you for your detailed report and I
again apologize for the inconvenience."
I haven't seen them come out with the new ones yet, and in the meantime I found a different kind of cup drinker that is working wonderfully.
If they ever do come out with a better one, I'll be the first to try it! :D
