I bought this a few months ago and it has brought me joy. One thing that I didn't realize is that it is a bit louder than I prefer. Keeping it on a lower setting is the quietest setting I've found. It can catch you by surprise how quickly you may respond so dive in with that understanding.
Beautiful design & easy to use, but it's almost too intense/doesn't have a low enough setting to get any sort "build-up". It's also pretty loud, so if you live with others and have thin walls be conscious of that.
