Review
Super Pet is one of the most well known manufacturers of small animal products.
I have 3 of these, two 8 oz and 1 26 oz.
Very well designed, heavy glass bottle. One side of the bottle is flat so it fits snugly against the cage. Super Pet’s unique design “Double Ball Bearing” Drip Resistant Sipper Tube is quite drip free, except for a few drops after refilling it, as the vacuum forms. It has a floating duck making it easy to view water level.
All the rats can get to is glass and steel so it is chew proof. Easy to clean, bottle can got in dishwasher.
26 oz bottle no signs of wear but not so with 8 oz. bottles

There is very obvious corrosion in the small bottle metal cap where the spout joins. The metal looks to be chrome plated and not stainless. Maybe it was the manufacturer particular lot of the smaller bottles that were effected that were made not using stainless. The larger bottle is just over 2 years old, the smaller ones 3 years. Definitely different metals have been used as can be seen in the photos, center photo shows samller spout on left. The sleeve will not come off the small bottle.
