Curious if anyone has had any if the Deco units for a few years.  I recently purchased a 3 pack of M9 plus.  All three emit a lot of heat and are very hot to the touch on the bottom. More than most electronics than I've ever owned.  I found QA on their website stating they can run warm and that is normal become of the design. That much heat does make me wonder how long they will hold up. If anyone's had any issues with the heat or has had a unit for a long time with no issues I would like to know.  Trying to decide whether to keep or return.
