Yes sir, you're looking at a tiny 4.5 x 23 x 14-mm USB Bluetooth adapter with a hearty 100-meter range. It's also Bluetooth 2.0+EDR so you can expect to push a data rate of up to 3Mbps. Princeton's 10-meter adapter released in August now looks like school on Sundays -- no Class 1. Look for the PTM-UBT4 to hit Japan and beyond for ¥2,980 (about $28) later this month.
