-Good value for the price. Just can't beat it. -Works with PC , Smartphone very well. I can carry it to Kitchen and listen to the audios while I am working there. -Very suitable for a minimalist like me who doesn't want to place big speakers and subwoofers in his room.

Haven't found any so far. Probably having option to increase or decrease volume would be helpful. Right now its done through the device that is connected to it. I would also appreciated the battery option but again look the price tag. You can only expect so much.

In summary its a great purchase and fits into my requirements of having a lightweight speaker that can connect to Smartphone , Desktop PC and Tablets. I can carry it around in the house and connect it to smartphone to listen to the audios and YouTube videos I like. Way better than using smartphone's builtin speakers. no comparison. Price is a bonus too.
