We've had the EezTire system in our 2012 2551 for about three years and we love it. It's been rock solid with sensor batteries easily lasting two seasons.
One of the things that drew us to this particular system at the time was the fact that the display would show blank if data for a sensor was lost. Surprisingly this was not the case with some other systems that would simply display the last tire pressure if sensor communication was lost for any reason. I would guess that things have changed in the last few years but it's a feature worth paying attention to when shopping around.
For five tires (spare included) I used the cap-style sensors with their anti-theft covers removed to make them easy to screw on. For a little theft deterrent I always reinstall the rear hub caps rotated 45 degrees so that the hub cap holes don't align with the sensors. For the front I used some sheet styrene plastic softened with a heat gun to make little bulged covers for the holes that line up with the slightly protruding sensors. So all the sensors are hidden or covered and hub caps have to be removed to put air in the tires, but that's infrequent and not a big deal.
I can't recommend the EezTire flow-through sensors however, primarily because of their mechanical design. I bought these for the inner tires thinking that it would be less of a hassle, but a peculiar design quirk makes them very difficult to screw on for the first time and when you replace batteries. They have an internally threaded brass female end that screws onto the valve stem, but for whatever reason the threads start too deep within the female end. So as you fiddle about trying to get the first thread of the sensor to catch onto the valve stem you are just starting to compress the seal and depress the valve at the same time. The thread should have started immediately at the end of the brass coupling so that you could get aligned and have the threads engaged well before the seat and valve compression begin. Refilling the air that was lost during the installation is also an extremely slow process through the sensor - you can hardly tell that any air is going in. On top of that, they have a tiny socket head security screw in the side of the coupling that is very difficult to tighten.
But having a tire monitoring system is very comforting if you're the type that thinks about what those poor tires have to endure while you're cruising at 60 on a blistering day. I wouldn't be without one now.
