Has anyone used Cocoon Insulation?

They sell this at Lowe's and its a cellose insulation to be blown in to attics and walls. We would like to use it and blow insulation into our walls. We were wondering how good it is and how easy it is to do. We have the exterior of the house stripped already for new siding and would like to blow in insulation from the outside of the house into the walls. Any comments would be appreciated. Thanks in advance.
