I really liked this one until I realized the manufacturer was using the wrong glue which is not thermally conductive. I'm not sure if the manufacturer really cares, but Revain should stop selling them until they start using the right glue. You can see the 3M specs by searching the web for 3M 9448A. You will find that there is no heat transfer capability. Now I'm refining my project and waiting for the right glue to arrive.
