They are very good incubators. The humidity pump adds to the cost. It is usually about 90 more to get the ex. The humidity pump adds 126 if purchased seperately.
The Humidity pump sits outside the incubator and uses tubing to add water to a pad. The control unit turns on the pump.
It seems to add about $150 to $200 on Amazon to order it with it. Also about another $160 to get it separately. That puts it a little over my budget. Is it necessary or is it still a good one without it?
