It worked as expected. GPS was reliable. Using with a Windows tablet computer to access GPS signal while on the road.

Firstly, I'd like to get out of the way that I'm not an expert, just using this for accurate time, location, and messing around occasionally. In my, albeit not super accurate or lab controlled testing, this module has performed very well. And for $15 you can't really complain. The first GPS lock didn't take long at all, which surprised me because most of the reviews mentioned that it would, my 1st lock took about 5 minutes. The module seems to operate even without a computer as long as it's connected to a power source. So when you see a blinking green light, you know you've got some sort of GPS lock. The quality of that lock can very greatly, but you should at least have 2 satellites locked. I decided to try it on my Windows 8.1 PC, so I downloaded the software and driver from the U-Blox website, after then installing the driver and starting the software I plugged the GPS receiver in with a USB extension cable and set it next to a window. After around 5 minutes, I saw a flashing light on the GPS receiver and a I saw a few satellites were locked on in the software. After about 10 minutes I had 7 satellites locked, and 10 that were being heard. There was some minor drift in speed, altitude, and latitude/longitude but that's to be expected, even in modern cell phone GPS receivers. For a cheap little USB dongle, that I'd say that's pretty good! I should also mention that was indoors, so no doubt I'll have better luck outside. After that, I plugged it into the device I intended to use it with, a Raspberry Pi 4 being used as an amateur radio field computer. As soon as I plugged it in and configured it properly, I got a lock and an accurate grid locator, and more importantly I got accurate time down to the second, which is what I wanted since the Pi doesn't keep time by itself unless you use an RTC. Overall this USB GPS receiver works exactly as intended, and actually looks pretty nice all things considered. And for $15 it really can't be beaten. works very well, and I'll probably end up buying a few more in the future. 10/10

Excellent
