This bag stunk to high heaven when I opened it. An awful plastic/chemical smell. I washed it with warm water
and soap and aired it out overnight. That resolved the issue. The cover is easy to unscrew and the mouth is large. I could fit a couple of my thin ice cubes at a time, and i could easily fill with water from the sink. When filled the bag covers a lot of surface area. It stays both cool and hot for a full 20 minutes which is the amount of time I like to apply hot or cold therapy.
I give the Naniga Ice Bag 4 out of 5 stars. The initial smell was awful, but after a wash it dissipated. If the paint didn't wash off/move around, I would have given this bag a perfect score. It's simple and convenient to use. It's portable, so I will bring it when I in my medical kit when I travel. It keeps it's contents warm or cool for as long as I need it. It doesn't leak and it's very comfortable. I would recommend it.
I received this product at a discount. My reviews are 100% my own, honest opinion.
