So, Here Is Pros & Cons From @doodleman:

Pros: I feel if this app is very useful, what else to see for this era, many of us are very fond of listening to music. One of the features that I am happy about this product is the water resistant feature that allows us to take it on an adventure, like camping in the forest and other things.

Cons: I feel for the size of a portable speaker, the size of the device is too big, so it's a bit difficult to carry around.
