I bought one the last time the were offered. Sent it back. Difficult to use and the signal latency made it useless. Sent it back
I just received mine, and it doesn't work at all. The power light comes on, but there's nobody home, no sound out of it at all.
Mine was big-time FUBAR. It would intermittently just turn off, on USB or on batteries. It's not like it would just turn off then back on. You'd have to restart it every time, and no matter how I did it, no sound. Total Junk! Of course after I boxed it up and dropped it at the UPS office, I get home to find the instructions are still on my desk, DOH! I hope that stupid mistake doesn't cost me $27.
