It is waterproof, and we are using it inside the shower door!

This is an honest reviews from a customer that purchase this product!

PROs: it's small, but not very small.  Connect to my bluetooth note8 automatic.  The time it takes is less than 3 seconds.  Not sure why other reviews take long time to connect. It's waterproof.  It cam with manual/instruction + a plus bonus string so we can hang it at our shower door!  It also come with an a/c adapter so you can connect to your phone if your bluetooth doesn't work.  Overall i'm very happy with it; however, please see the cons:

Cons: Sound is small, we can still hear them during shower, but we expected it to be louder.  My note8 phone sound is louder than this portable.  The bass is a little weak.  Maybe I expected too much from this tiny guy.  Oh 1 more thing, the microUSD charger is not come with this product.  I have plenty around the house so finding a charger is not a problem.
