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.
