Vivitar 5 In 1 Bluetooth Fitness Tracker

[1] I bought Waves NX Head Tracker to use it with Logic Pro X in a Mac Pro Mid 2010 OS El Capitan and Bluetooth 2.1 I needed Bluetooth 4.0, so I bought this StarTech adapter. Plugged into my computer, but it was not recognized as BT 4.0. Then I downloaded Hardware_IO_Tools_for_Xcode_7.3.dmg, and installed Bluetooth Explorer in the Applications folder. Opened it, Tools menu and choose HCI Controller Selector, I clicked at the arrows and selected Broadcom Corp and clicked Activate. Done My computer recognized the StarTech adapter as Bluetooth 4, and I was able to use my excellent Waves NX Head Tracker.

5 Stars. It's what we needed.

[1 x SmartMedia] Does what its suppose to and reliable at a fair price. 5 Star purchase.

[1] This watch is a very good one for the price. It will tell time to tracking your fitness goals!!

[1.74 lb] Excellent service i caint say enough good things about this company, customer satisfaction no.1

[Glass] I use this while shooting weddings. 5% for me is the sweet spot. Its very subtle where you really have to look for it. Due to it being so subtle one can use this in about every situation and never have to take it off. The only time one may want to consider taking it off is shooting a reception.

[LCD] This is my second one. I updated for the RGB option. My first one was just white. This version also dims all the way down to zero, where my 1st generation one only went down to 5%

[0.17 lb] I bought the 5% for my RF 35mm 1.8 and it does a great job at diffusing the lights but very subtly. You can barely tell and that might be a good thing depending on what you are shooting. The filter itself is very solid. I wacked it against a railing and I thought it broke, but it actually scraped the paint off of the railing.

[7.2 x 4.8 x 2"] Charger is slow to charge from 5% battery level, and works best with one battery attached. Does not overheat.

[1] item as described;great price;quick shipI.I WOULD USE AGAIN.5+++++ stars my rating.
