La máquina está muy buena. It’s pretty loud though and it gets louder the higher the intensity.

It gets very cold very fast, but it seems to warm up kinda fast, almost as fast as my jade roller. Stays cold, clean and much better than my gua jade roller.

The ice roller squeaks so bad it's hard to use because it is so loud! The cheaper 5-8 dollar plastic rollers work better and stay cold longer. Says it is stainless steel.
