I got one of these a month or so ago and have had no poblems with it. It's really small as well, about half the size of my old BT dongle. I'm sure it's not really 100m but still conects to my phone when the phones upstairs and my comps downstairs, can't get any further away in my house. Got mine for 1p, plus stupid postage of cause. Cost me 6.74 in total so it a little cheaper now.
