I was thinking it could be just these cups. I may try again in the future but I think these will go back, otherwise I will have $25 into it plus new cups, don't know that it's worth it for this particular waterer.
Thanks!
I think the cooler is a neat idea as far as helping with temperatures but I agree. $25.00 is a little spendy and if they don't work they definitely need to go back. I only had an occasional one out of the 4 packs that didn't;t work right.
