I am one who swears by the Choco Nose H128 Patented No Drip Small Animal Water Bottle. Mine were purchased from Chewy.com and also available on Amazon. I have 4 of those bottles and after a year and half of use, one has started to drip. The most common complaint is the bottle size is only 11.2 ounces and some people prefer a larger bottle. You can easily use the nozzle with a larger soda bottle instead. The other issue is that you should tap the metal ball inside the nozzle to ensure water comes out. I've read one Amazon review where the buyer did not tap the metal ball inside the nozzle and no water was coming out, which led to his hamster dying from dehydration. Other than tapping the metal ball, I watch to make sure bubbles come up when my piggies drink. I usually only fill my bottles half full as I have only two piggies and use two water bottles at any one time. I am happy with these water bottles and would purchase them again.
