Just so you know, you can blend the sounds at differing loudness which is very unique and helpful… I have it going 24/7 at our air return box which vents to mine and another’s rooms. I feel better masking the noise and the cafe sound is great for that! There are a few weirdo sounds on the looped choices though which are odd like a cats meow in the thunder choice but it takes a while for the loop to come back around so it’s not that terrible. The cow noise cracks me up…. Moooooow. It’s pretty great. Makes me wish I could record my own loop tho.

The ability to mix sounds is awesome! It works really well.

Some of the sounds are goofy

If this was $30 it would probably be worth it to someone who needs sound to fill a void while awake. The sounds are all bad for sleeping. The waves sound is more like a lapping lake. Rain has birds intermixed, rest aren't for sleeping (cows, cafe, crickets...). If the speaker had are least a decent mid range maybe it's worth it, but as it sits this is a $30 item to make sounds while studying or working.
