Moisture/Tensiometer recommendations?

I have been looking for a decent moisture meter or a Tensiometer, I don’t need to hear the “just lift the pot, or stick your finger in the pot” answers. I really just want a good meter for training and other needs. Has anybody tried a Blumat 50205 Tensiometer? Seems to be the best one on the market but I really just want to hear everybody’s opinion! Thanks in advance.
