I have 2 different Acurite Hydrometer-Thermometers. Which is better? pictures

I just got 2 of these today from walmart. Both do humidity but one has an additional temperature sensor.
Do I keep the dual sensor one ($11) that has humidity only on the unit, or buy 2 of the other item ($7) so I have 2 humidity sensors?

Keep the probe one. I actually have both, the one w/o the probe for snakes that require a higher humidity. :gj:

i was contemplating them both, but i bought 2 of the probe ones and i love em :)

Probably a good idea. The big thing with these guys is fairly frequent battery changes for accuracy....at least with my experience.
