Review: BEST OF THE BEST UNTILL NOW AND EVEN BETTER THAN BELKIN PLEASE READ THE PRODUCT DESCRIPTION CAREFULLY - I am a guy who normally work on computers and spend most of the time in front of my computer. I have a engineer degree on computer so I know abut this stuff. I tried many Bluetooth dongles, from the cheap ones to the expensive ones, but in here it fits the phrase that says As more expensive, better the product, well in this case it is true, but with this product it is not necessarily that it must be too much or crazily expensive to be good. Some customers clime to have problems with this dongle and some others asking some questions about this product PLEASE READ THE PRODUCT DESCRIPTION and this review so may help. I consider up to 20 dollars for a Bluetooth dongle is a good price. This dongle it comes with a very very nice software that connects everything automatically and recognizes everything instantly and will make a profile, if it has, of the product you have. For example I have my keyboard connected via Bluetooth, I also normally connect my JLab GO Bluetooth Wireless Headphones and the software of the Iogear Bluetooth creates an specific profile for my Bluetooth headphones and it creates another one for my cell phone, a Note 2, so the profiles works for you to control specific stuff of the devices you connect which is excellent and only expensive devices comes with such a software. I tried with the 2 dollars bluetooths and those burnt out or stop working in around 4 months. I bought this Bluetooth dongle about 4 months ago after my cheap ones, (2), bunt out, so I strongly recommend this dongle to anyone. Just pay a little bit more extra and don't get a pain in your butt suffering for cheap products, this is the real deal. There are some customers claiming that they need to upgrade or reinstall or uninstall and re install the software that comes with the Cd. Well normally even when the dongle claims to be plug and play, PLEASE INSTALL THE SOFTWARE FIRST BEFORE PLUG IT IN, generally every single product now days you have to do that install the software first and then restart your computer and then plug the device in. if that doesn't work then you can download the software from the webpage, but for me that won't be necessary. I am very happy with this dongle. Hope this review helps. Oh and PLEASE DO YOURSELFS A FAVOR.. READ THE PRODUCT DESCRIPTION BEFORE ASKING QUESTIONS... This device SUPPORTS UP TO 3 SIMULTANEOUSLY CONNECTED BLUETOOTH DEVICES AT THE SAME TIME BUT NO MORE THAN 3 otherwise the dongle will run it crazy. Thanks
Review: Great fix for persistent BlueTooth issues on Apple Mac Pros! - This is a great solution for a pervasive problem with Apple's Mac Pro systems through 2013. I have not tested the new "late 2013" rount tower model, but all of the previous designs (Mac Pro 1,1 through 5,1) have Bluetooth antennas on the bottom of the case resulting in very poor performance - especially with the Magic Mouse. This adapter solves the problem and upgrades BT to version 4.0 BT LTE. The chip set is Broadcom, which is used by Apple. I think, starting with Mountain Lion the shipping kernel extension recognizes the chip and device, there is no extra driver software required. Previous versions required some editing of Info.plists. I simply plugged mine into one of the USB inputs on the back of the Cinema display. Based on reports I read, in some cases the system will automatically select this devices over the built-in ones. In my case, I had to use the BlueTooth Explorer available as a developer tool to activate this device as the system BlueTooth Controller. I also needed to pair all my devices again. But now, there is no more lag. Alas, it is not (yet?) recognized in Yosemite as a device suitable to allow hand off... Comment after some use: The device is not recognized during the EFI boot phase. This means that you have to use a USB connected keyboard for parameter reset, option boot device select, and entering the pass phrase for FileVault2. I always have a second USB keyboard connected, since this was also unreliable with the built-in controller. Otherwise, BlueTooth is now working great with Yosemite and Mavericks. I have not been able to get it to work properly with Snow Leopard even with an edited KEXT, but that configuration is not officially supported anyway. The controller is recognized, but I was unable to pair devices in a short test. I only use this for some old games requiring Rosetta.
