Doesnt matter how great the Mamba wireless functions, its just a 100 dollar ($88+tax as of now) paperweight that functions once in a while as a mouse. However, I had worn them almost every day and liked them enough to buy again despite the premature failure. Ive been buying these kinds of mobile speakers all the way back to the wired days, and its amazing to see the technology progress. I only want a phone. This old dog just learned a new trick. Which isn?t really what I needed. onths but I dont think theyll make it into next winter And again, she said these are the best! Plus, there is a hard border around the edge - stepping on it is like stepping on hard wire. Amazing !
