I ordered a set of 10 on 2/8/08, and asked they ship the existing sensors (they told me the new style would be delayed for some weeks).
I received the system in a couple days, and it looks good, but I should have checked to see if valve-stem sensors would work on my MH wheels; the won't. I have a style of alum wheel (accuride?) that has oblong slots, as opposed to round holes, around the wheel. Not enough room to install the sensors, s0 I may be returning or selling the system.
