Fitbit Introduces Charge 2 and Flex 2 Fitness Trackers

My first activity tracker, Vidonn X5, worked reasonably well and lasted for over a year, but the subsequent models I tried were all mostly disasters, especially as they added some features like a heart rate monitor that did not work reliably, and worse, their lifetime was poor, lasting only a few days to a few weeks before stopping working. My Xiaomi Mi Band 2 died last week-end, two days after a firmware update which decreased battery life to less than a day, and now refuses to charge. While the HRM was utterly useless, it did count steps fairly accurately, and battery life was good. Sadly, it would only last about two months. So at this stage, it might be worth spending more for a fitness tracker, and Fitbit has unveiled two new models with Charge 2 and Flex 2. Fitbit Charge 2 includes a 1.5″ OLED touchscreen display, and an […]

I also added Ethernet and HDMI cable, and finally connected the power supply to boot it up. But as you can see from the picture the very first boot was not […]

Last week I publish the first complete review of an Amlogic S905X device with MINI M8S II TV box review, and while the device work in a smooth and stable manner, some features did not work as expect such as HDMI audio pass-through. I’ve now had the change to compare it to another S905X with NEXBOX A95X, not to confuse with its “homonym”: NEXBOX A95X with Amlogic S905 processor. I’ve already taken pictures of the device and accessories, and checked out the hardware in the first part of the review, so today, I’ll report my finding playing with Android 6.0 firmware, Kodi video and audio capabilities, and check whether bugs and issues found on MINI M8S II are also present in the device. First Boot, Settings and First Impressions NEXBOX A95X is really a tiny device, so it’s no surprise that it only comes with two USB 2.0 ports, and […]
