Worked well at first, but unfortunately water seeps into the bowl as several others have mentioned here, which is a dealbreaker for continued use of the product, unfortunately. Once the water gets in during washing—whether you use a dishwasher or wash by hand—it can't be removed. Really a shame, because they were super nice and a great size.
Be careful with this feeding bowl. The top edge isn’t sealed watertight, so when you wash it, water seeps between the inner and outer layers. This isn’t hygienic, as it’s pretty much impossible to get it out again. Over time, this could pose a health risk for your cat.
From the reviews I’ve read, it seems like it only happened to me: water gets in between the blue coating and the steel, and then it’s hard to get it out.
Looks nice, but it’s better to spend a bit more…
