BT-S2 1000m Bluetooth Headset Motorcycle Intercom at Gearbest.com

Has anyone tried this unit. Its $31 at gearbest.com on a flash sale that OOTV turned me on to with a camera purchase. I ordered it just for the price. If no one has I will let you know my opinion. But for 31 bucks vs. Sena 2os at $269. You can buy 3 for a ride with 3 buddies for less than a Bill! Obviously not amazing, but for the price and the online reviews seem to state that for the money for listening to music and phone calls it works pretty well for a solo rider.
