A very good speaker at a great price. One of the best I have found under $50.
Has really good build quality.
A good budget alternative to speakers like JBL Flip3 and Sony SRS-XB2.
Has a fairly loud max volume, and really good bass response to well below 70hz.
Only flaws I have found are a fairly high self discharge, another words if you let it sit several weeks the battery will probably be low. 2nd At higher volumes, the speaker may dance around a little.
