Product purchased in November 2012. Commissioning easy road. It took reformat the hard drive. Very easy programming. Very good quality recordings including HD. For now, only problem when we want to delete a part of a record (pub) it is very long and sometimes the device does not clear and it "bug" you have to do a reset. However not regret buying this unit because it is what I wanted, namely, recording DTT in my absence and when I look at a string and I want to record another.
