are these any good?

the only bad part is that it cant measure two places at once.i got it yesterday while i was at petco,somehow these showed up out of nowhere.

Far from top of the line, but not in the lower ranks by any means. A PRETTY accurate reading about 90% of the time...just make sure you dont keep it anywhere near the water bowl...ive had 3 of them fall into (dragged into, rather) the water...no bueno. lol

Not worth the price tag on them, though.
