Flents® Water Bottle

I was skeptical about a rubber water bottle for heat therapy, but after using it for a few days on my sore back, it really does help reduce inflammation. The way the material conforms to the body makes it much more comfortable than the hard plastic ones I've tried before.

I was a little skeptical about how well it would hold heat, but after five minutes in the microwave it stayed warm for a solid two hours on my sore lower back. The rubber conforms nicely without feeling too stiff.

The rubber conforms to your body well enough that I barely notice it when I’m lying on it, which is great for a sore shoulder. Heating it up in the microwave takes a bit longer than I expected, but the warmth lasts a good while. Solid for the price.
