I use a Humi Care EH (

Got it after I got tired of constantly (ok thats a bit of an exaggeration

) refilling my credo's. Modified it to use Cracked ice with prop gly. Also use an external fan to pull circulation to my top shelf.
Works pretty fair. Only thing that sort of annoys me is the low moisture alarm is really quiet, and the unit does not store your previous settings when the power goes out. (I plugged it in to my APC UPS...yeah I'm weird

)
Otherwise works like a charm!
Only thing that aggravates me is I can't seem to find the external remote as a separate piece. Would love to expand the system by obtaining one.
