Some concerns. Pressure reads low and now I have to find the special tool to remove cap to inflate. Don't I still need a pressure gauge for proper filling? Extra weight on wheels? Will the they need to be balanced? Over time, will the seal crack and actually cause a tire to deflate? What about the fifth tire (spare in trunk)? Would it not be prudent to monitor it as well, you know, just in case?

oldgearheadyes, actually filling your tires becomes slightly more of a hassle, unless you throw more money at it and get a "t" valve stem *edit to add - or choose not to use the lock nut. earlier posts have addressed the weight question, it appears to be a non-issue. metal and regularly replaced rubber/plastic valve stems will not have issues, aging rubber/plastic valve stems will, with or without this product attached to them. "xtra" valve caps can be purchased and added to the base system for things like spares and trailer tires.

phoiblesThats a few interesting questions. Ill toss another one, where i live we get awefully close to the -40c operating temps. Would those report false readings or simply stop functionning past -40?

KaozerI'm guessing it's mainly a limitation of batteries to power anything at those temperatures. Your experiences would be determined by how old the battery is and just plain old luck.
phoiblesI funded this project on indiegogo.. I've been using it for over a year on 2 cars.. and it works very well. There has been no issue with seal cracking throughout the seasons. I don't bother with the lock nut.. it's really not that effective anyways. You can still remove the sensor without the tool.
