Just picked this up the other day for around 29.99. Its an acurite remote thermometer/hygrometer with probe.(model #00592W) I keep the base on my desk, i dont have to keep going in to check her temps anymore. the temps on the top are the room temps and the one on the bottom are the cage temps, plus you can buy additional thermometers(up to 4) to work on different channels with this thing for additional caging. I love this thing so far. The only setback its a little tricky to get going but its still worth the money
