SpeedoHealer provides a very rare moment of consumer joy for the UK based TJ owner, an item that costs less here than it does in the US 
A great experience with Blue Monkey Motorsports (the company who sells the SpeedoHealer)

The 12oclock labs has the correct waterproof connectors making easy to install. I did not have any problems calibrating mine. Are people having issues with 12 o'clock speedo calibration? The price is also a plus.

I haven’t read of any issues but people are passing 12oclock because of the data entry.
I’m stuck between healtech and 12oclock.

Skip to 7:00, it really isn't that hard. I wonder if somebody had a problem and gave up. Then spread it on the internet it's too complicated, because it isn't. I was able to use a GPS app on a phone several phones ago to get the correction factor. This should help with calculation.
