ITM Porsche TPMS sensor battery dead after 1 year!

Anyone have their battery go dead after replacement? I had a new set of the ITM TPMS I purchased for my 2nd set of wheels on my 911 go bad this week. I had my tech check them and he found 2 of them had dead batteries. Is this common? Im kinda pissed I have to get another set so soon.

We have seen the ITM sensors go bad fairly quickly. I have also seen the the ITM sensors do not send all of the same data as the OEM sensors.
