LG, I'd actually looked at that one. I need another thermometer or two (for playpens outside and for when we quarantine in a different room). The only thing I'm not crazy about for that one as an in-cage thermometer is that there isn't a probe, so the thermometer itself has to go in the cage, and it doesn't show you the inside/outside temp (cage vs. rest of the room) like the one I linked to.
