In use, very good. When not in use, kills batteries
I'm using this GLO on a Nexus 6. After installing an app called 'Bluetooth GPS' and enabling 'mock location providers' in a hidden menu 'developer settings', it works very nicely. I first had to do something about the fact that this GLO comes without a battery or battery cover. After confirming that the battery pinout is the same as most phone batteries, I soldered some leads right to the connector pins and used 3 Ni-Mh sub-c cells to make a power pack. Pack cost me about $3 to build out, has 4.2 volts on my RC charger and 3800mAh capacity. But, leaving the battery pack connected with the GLO turned off drains the pack completely! It could be from not using the sense feedback, though I doubt that. Could be why this GLO is missing parts, if it was a warranty return item. Other than needing to disconnect when not using, it works just great
