We have 11 8000's and 3 Caleo's. the reason we do not have any more Caleos is because the nursing staff do no t like them. If there is an 8000 incubator available, they will choose that instead of the Caleo. Servicing the Caleo is a lot more time consuming than the 8000. I can service 4 800's in a day whereas I can only service 2 Caleos......
