The gel is good at 360°, it's cool even though it hasn't been put in the fridge yet. I was able to put it on my wife's head but it's still oppressive. I don't know if my boyfriend will tolerate it because I mainly bought it for him. We'll see if the warm function is pleasant.

I haven't tried yet. Looks solid.

Nice, fits well. Heats a bit unevenly in the microwave.

I purchased the 360. As soon as it arrived and I wore it, it felt cool and had a nice tightening sensation which made me feel comfortable. I suffer from migraines and frequent headaches, so I hope this product can help alleviate them.

very good, it has gel on both sides.
