Good price and fast delivery!

My grandchild requested this speaker as a birthday gift. Walmart had the best price, and very fast shipping. The speaker arrived in plenty of time for the birthday and my grandchild is very happy with the speaker.

This is a gr8 item. Nice because it's compact with a punch in sound for its size. I use it on my bicycle %26 when I go for walks. I bought a velcro aparatus so I could strap the item on my bicycle. Not disappointed at all with my purchase. I also bought a carrying case so I can store it when I'm not using it, which also purchased from Amazon. Highly recommended.
