Product review (1 stars): Very poor design
I have 2 of these running in a 6 foot tall cabinet humidor.
The foam blocks stop holding water after a couple weeks.
I've replaced it with both floral foam from a hobby store and bought replacement cartridges.
With two of them running full time 24/7 after a couple hours the humidity will finally get up to 70%.
 but the alarm goes off telling me it's dry, and the water just runs off the block.
I'm gonna nut up and get the oasis magna 2.0.

Update.....it died, the main fans just quit.
So I hit the return button.
They shpiped a replacement BEFORE I sent the broken one back.  Of course if I fail they will charge my card for it, but I am very impressed with the customer service of this company.
Ok, the replacement came out of the box broken.  The DC out port will not allow the strip to be plugged in.
Don't waste any money on this.
