It gets warm in less than 20 mins. It’s hard to put on by yourself & it’s not comfortable when your laying down. Which I’m doing a lot of since my surgery.
It’s great the first 10-15 mins. Then it gets warm & just get it your way. I end up using my Thing cuff more because it stays cold longer & I can move it where I want it.
It isn’t meant for women that are well endowed either. If I move the Velcro doesn’t keep it together & it twists all up to my neck
This style can easily be put on with one arm as opposed to the new version. Not sure what they were thinking when they designed the new one, but I tried it and it was impossible to put on with one arm immobile! This style also provides compression, I love it!
