i just picked up some clones in the bubble (the pix are here somewhere under teh dont get scammed thread) from a hock shop at 12 bucks each. they went through 4000 in under 1 week!
anyways i just got the 35, 45 and 57 hz frequencies. the 27 hz works on the same as a zipzap or bit. but the fwd is reverese and viceversa!
cool to at least have some of the hard to find frequencies (or illegal)
