I got a set from Tire Rack along with the wheels and winter tires for the 2010 Jeep and they work perfectly. On the second winter now. Did not have to do anything except take a short drive to sync the TPMS sensors and then the same in the summer when the originals went back on.
I also did the same for my new 2011 GMC truck last month. I had to follow the reset procedure in this case as expected but no problems encountered.
Apparently whatever they are selling work.
