Mine works like a charm. ~10 months so far. Temperature agrees pretty much with a hand held IR gun but it is a little hotter inside than outside the crankcase. Level works well too. I bought it with the bike so its under warantee perhaps that's why it is still working...
I like mine, but the digital readout for the oil level isn't correct. When the oil is a little over half way between the full and add, the readout says it's overfull.
