TPMS Tire Pressure Monitoring Valve Stems
Kind of a basic question, but I have a couple of questions regarding these.
1) Do you use these on your bike? Why or why not?
2) Would you use these on your bike? Why or why not?
3) If you do use these on your bike, what is considered to be the "best" in terms of quality, accuracy and reliability?

Back when pressure gages were only mechanical in function there were a few attempts to have a pressure readout built into the valve cap. The shops I have been in generally found these caps to be hard to read exact pressure levels and added bulk to the valve stem. They never caught on with the buying public. Perhaps the ease of using a hand held gage and the ability to better discern between the gages' markings (being larger) was decided to be the better way to monitor pressure levels.
Then there's the question of whether a few PSI difference from the "best" level to what is really in the tire is really an important difference to be concerned about. I think not. Andy

Given their very-low cost, are these still not worth spending money on?

When I pump up my tires to the desired pressure, I give them a squeeze, and try to remember how they feel. If they become noticeably more squishy, I am usually down 10 - 15 psi. I pump them up again, sometimes with a frame pump that has no gauge on it, if I notice it on a ride. This allows me to keep the little black plastic valve stem caps, or the Peaty's ones with the valve core remover and spoke wrench built in.

Regarding expense, I was looking at TPMS monitors that are sub-$10, like this Specialized solution here, for example:

The TPMS valve caps you linked to only work on Schrader valves so that makes them unusable for the big majority of riders here who only use Presta valves. Also, automobile TPMS valves relay their information electronically to a readout in the car. These are just manual pressure gauges scaled down to a too small size to be really useful.

Would never want one of these. A complex solution and extra weight for a simple task for every bike owner. Given you use the same tube and tire pressure you can estimate how many days till you need to top up on air. Thumb-O-Meter can tell if you have a slow leak. Simple.

I’d actually like some for my commuters that could be paired to my phone so I know what morning I needed to air up the tires.

I know a couple of people with them and they like having them.
If they were cheaper, I might have them on a velomobile or recumbent where a crash can be very serious.

I don't consider the specialized part to be a TPMS since it only indicates if you are above or below a given pressure. I've known a number of people that tried the same type of device on motorcycles and most complained that they didn't seal that well so they ended up losing air much faster than without.
Personally I generally know when my tire needs air so would not bother but hey, it doesn't cost that much so give it a shot and see if it's worthwhile.
