Super accurate

It consistently pulls in higher frequency than 18hz.
The magnetic base on the antenna is great.
I ended up using a shorter usb cable that I had laying around, I didn't want a bunch of cable under the dash

Mounted the antenna on top on the dash, parked inside the garage under the insulated aluminum roll up door and surrounded by 70 foot pine trees. Not a problem, all 18hz available!

Brings phone telemetry nearly to the level of dedicated track hw setups at a fraction of the cost

The best way to get faster is seat time. The next best way is to analyze your seat time and find where you're losing time. Using just your phone, every app on the market seems to only store data as fast as the selected GPS, which with your phone GPS selected means you are limited to 1Hz. I went with Harry's and an OBDLink MX+ and was frustrated because steering and throttle inputs, as well as track position, are just about impossible to analyze because a 1s resolution is a huge amount of time on track.

I purchased this and it works flawlessly as an external GPS with Harry's Lap Timer. Now, I have both the OBDLink MX+ and this GPS as sensors in Harry's and the difference is night and day.

I took a few screenshots from Harry's from my fastest lap at MSR Houston with the phone GPS and then my fastest lap at ECR with this GPS and I've put them here for comparison.

Hopefully it's obvious from the photos, but the increased precision allows you to actually see your inputs to a much greater degree.
