It seems to work. I guess there might be more functions the driver could implement. Perhaps better support for self-survey or logging or whatever. I'd like to see internal temperature logged. But for normal NTP use it works fine. If you only have one GPS the t-bolt is the one to have. But if you can afford two there are lower priced GPSes that use less power that work well with NTP. I have the t-bolt and two UT+ units. Whatever you get make sure it is a TIMING gps. The Garmin units and the Sure Electronic board at not timing GPS although they do have PPS outputs. They work but they are "uSec" level devices. I'd look for 100ns or better.
