That is extremely cheap pricing.
I have had my setup running for over 6 months, admittedly with a few minor hiccups, but that is proably due to both my own incompetance, and laziness to sort it out thoroughly. Seems every time I think of spending some time on the TPMS, a friend and a beer consume that timespace. New Year's resolution. "Sharpen Up".
I would at this time wish to pass on my thanks to those pioneers who have spent many painstaking hours designing, building, sourcing, testing, troubleshooting, and patiently listening to whinging from dumbo users like myself. Yes, I know. I should have thought of plugging it in before complaining of it not working.
Just to name a few, there is of course Robby (El President of TPMS), Dejan (Dr Who of TPMS), Mr Bean (Professor Thinktank), Wolfgang (Prof. CF), Lok, Enforcer, Juve021, just to name a few.
