Works
Does what it's supposed to. Make sure you float it in the aquarium to bring the temp to match.
Impossible to Calibrate
Of course you have to purchase this or forego one of the primary functions of your Apex... but the calibration is horrible. Took me weeks and around four tries to get it close. At this point I’m not even sure whether to believe it or not.
