Has anybody had an issue with the Fluker's Hyrgromometer and Thermometer pack? The one I'm talking about includes two separate units with gold rims. The hygromometer has a frog on it and the thermometer has a sun design. I recently bought the two-pack for my new crabitat. Previously I was using the ZooMed combo made specifically for hermie crabs (As long as both were in the yellow the temp/humidity were at ok levels...) which to me seemed like just another cheap hermie gimmick so I bought a new Flukers version... The Flukers version seemed much better to me, however now I'm doubting myself. The needle on the Flukers hygromometer seems to stick sometimes, when I tap it it will move (I now tap it quite often)... and I don't know if it's reading right at all. At first I thought maybe it needed to be calibrated, but now I have both the ZooMed and the Flukers in my new crabitat, and although the ZooMed changes upon leaving the lid open etc... the Flukers does not, and the needle isn't stuck now. The ZooMed hyrgromometer was at 90 when I put it in, so I left the lid open for a while and now it's at 80. However the Flukers has been at 80 all along (tapping it hasn't even made the needle move).... Sorry this was so long, basically just wondering if anybody else has had a problem with this Flukers product?
