Pros: This tiny USB Bluetooth adapter is a modern day miracle. It worked immediatly, out of the box under Xp, Vista, 7, and 6 variations of Linux. I was able to hook my Wii controller up immediatly and od white-board work.

Cons: It's so tiny, earlier I thought I had lost it. It was just plugged into my computer, barely noticable. Not a complaint, but it's so small you actually have a chance of never finding it!

Other Thoughts: You can easily plug this into the back of a computer and use it for bluetooth headsets, Wii controllers, PS3 controllers, wireless bluetooth remotes and any Bluetooth device you can imagine!

Bottomline: Don't buy one, don't buy two, buy 4!
Four is the magic number, it will give you plenty to keep and a couple to give away or trade. People will be amazed at it's size and think you paid a whole lot more for it!

Pros: This device really works as promised and do the job. Paired easily with cellphones (Nokia E75 and N95) used as modem and for file transfer. Also paired with my bluetooth headsets (Nokia bh-504, bh-104, and DX sku.8422). Very small and descrete.

Cons: Does not worked so good with my nokia bh-504 while listening to music. playback is not continuous.

Other Thoughts: Unfortunately, Windows XP does not have a complete bluetooth stack. So, I need to install a copy of blusoleil software to handle my audio devices. No problem with Ubuntu 9.10, as it haves a more complete bluetooth stack with A2DP and HSP/HFP. Keep in mind that it is not a device problem and it does what it needs to do.

Bottomline: I got one for my office workstation, and other for my netbook. I'm buying now one for my home desktop and a spare one. Still need to test with windows Seven and OS X.

Pros: Very small bluetooth adapter, you can leave plugged into the laptop all the time. I don't have a windows PC here right now, but this worked in my UBUNTU 9.10 Laptop the moment I plugged it in.

Cons: Some on the user photos are not so good.
you see it does not fully insert into the usb port. There is a gap of about 3mm on my eeePC 900. My Sony VAIO however looks very good because the usb port is ever so slightly recessed.Power couldn't be too high, but hey your worried about security right? you'll not pick up unwanted signal.

Other Thoughts: Buy about five of these. WHY? ever wnat to copy files from someone. If they don't have the Bluetooth you'll need two. Great way to transfer files and they'll want to keep it then. WELL for two dollars DONT BE STINGY. Think I'll be ordering more for all my friends.

Bottomline: It's less then $2 fits good, good build!
Just plain works as advertised.
Even if it was not but worked STILL WORTH $2
Don't be cheap, Buy one for your mom and uncle bob.

Pros: --> The primary thing is that it is really cheap (I really pray that it keep going like that) one like this here in Brazil is almost 300% more expensive :(.
--> The second one is that it is really small, inclusive I already forgot it in my desktop at work several times :\.
--> Really Plug an Play, I think that it is auto explained.

Cons: --> The distance could be longer… (too short for me, but for the price I don’t care to stay together :D ).
--> Been so small is good, but some time you can loose it if you don’t pay attention (it happened to me, that’s why I bought it two times :P ).

Other Thoughts: If you don’t have one you MUST buy it! It is too cheap that worth.

Bottomline: Sometimes you haven’t a cable or your desktop at work have the USB blocked up for storage things… but usually the Bluetooth device is windows native, so the windows recognize it automatically and you can send or receive files using your cell phone as the storage device :D
