This is my second cartridge and it's working better than. my original. Very happy with this replacement

Clearly these cartridges have been sitting on the shelf a while. The factory (Oasis) pre-charge has evaporated, but the foam is still viable for use.

Good product - Easy to order -Fast delivery

I have had the WiFi since April 2015 and I am a little disappointed. I have the Oasis Ultra 2.0, and on a couple of occasions the humidity has dropped below the set point of 70%, has gone down more than the 10% trigger point and never emailed or texted me re; lo H2o. The unit itself, Oasis module, does beep and alert, just not the WiFi function. I am currently working with Cigar Oasis and the engineer on a fix for this problem.
