pretty decent

UPDATE:
I've had time to continue to collect various data points and program this and a NEO-6M (both in CircuitPython/Python and Arduino's C/C++. I've decided the Adafruit Ultimate GPS is decent for most beginner projects (Adafruit's goal as I've read from them....I'm certainly a huge fan!).
In Western Washington, it closely meets its' spec of being within 3 meters when I'm in a cul-de-sac without trees or buildings for 10-12 meters. I had one-time, single position under 2 meters, but this is a single data point from many. Generally, it seems to put me about 6-10 meters from where I actually am for this region.
In the Great Flat Plains of Kansas, where the only thing in sight is the edge of the Earth in all directions, it is better being within 2 meters.
Taking the same positions from my NEO-6M, the NEO-6M just puts me spot on (
Having spent several hours programming both, I think the CircuitPython makes the Ultimate GPS a super product to get going. There might be better accurate data from this device as NMEA sentence it pulls data from, the GPS position is slightly different than at least one other sentence. This might be why the NEO-6M presents better, the CircuitPython pulls the information from a different NMEA sentence on the NEO-6M. My to-do list is to compare the sentence information from the same chip.
Original Review:
This took a couple hours to get setup using CircuitPython on a Feather M0 Basic.
It doesn't pick any signal up inside (unlike NEO-6M I also purchased). Once outside, it took a while to pick up signal, but was extremely stable in the location values it produced (where as the NEO-6M picked up immediately, although its' values had some flutter to them).
I'm looking forward to using both.

Worked for a robotics project.

Easy to use, just power it up and go. Couldn't get a lock with clear line of sight to the sky until I added an antenna, then it worked well.
Trust Adafruit -- Works well with Raspberry Pi

As usual adafruit delivers with quality hardware and solid instructions/software to help you use it.
I'm using this product with a Raspberry Pi3...follow the instructions for setup with RPi on the Adafruit website (use gpds daemon and the python 'gpsd' module. I'm using this as gps input for a python script running on the RPi.
Two CONS:
1. You will get the best results with an external active GPS antenna. With the 'hot start' the unit gets a gps lock in less than 30 seconds.
2. The lithium-ion battery that the uses is NOT something that is at every corner drugstore. You'll have to go to a battery specialist, or order online if that is an option.

Great little GPS

The GPS is very easy to set up and get running. The battery backup does work to 'warm start' the unit, but the use as a 'real time clock' feature is a bit buggy in the latest version of Raspian (Jessie) without recompiling the kernel. It also will not set the clock if it does not have a fix, so it can't be used as an RTC alternative in situations where you do not have a clear view to the GPS satellites.
Works well with Arduino

I bought this for a GPS guided robot project using an Arduino. Works well and gets a lock with-in a minute even in doors.
Some tips if you are going to use this on an Arduino:
- Baud rate is 9600
- You really only need to hook up the Tx pin to the Arduino, RPi or PC. (I don't know what commands you can send to it anyway)
- Use the "TinyGps" library in your project [...] to parse the NMEA strings from this GPS.
- No extra serial port? No problem! Use the "SoftwareSerial" library that is part of the Arduino IDE ... with that you can assign any of the Arduino pins to be an Rx/Tx pair.
- I soldered header pins to the bottom of the board so that the GPS antenna can be free and clear of any wires.
5 stars because it does the job!
