I was browsing through the net and I found this in Mudah.com. It look pretty obvious that the defi's that this guy is selling WITHOUT the sensors and for the Price.

Now I wont say that this item is 100% stolen. I might be wrong. MAYBE the guy lost/spoil all his Defi sensors and decided to sell his defi for a super duper cheap price. Anyway maybe any members in this forum that their defi's and other meter that been stolen able to recognize their belongings...
