The "twin tuner" characteristics displayed by Amazon (at the time of my purchase) for CGV Premio ST5 had motivated my purchase. Disappointment at the facility because it is not a "twin tuner" adapter. A "twin tuner" device can record one channel while watching a different channel. This is the first time I encounter an issue with Amazon. So I ask that devices feature checks are at least carried out before starting a display. Although Amazon's customer service has behaved as it should (reimbursement), I still ended up keeping the unit that was offered (which was not expected) to a family member who was about to acquire a "simple tuner." In summary this was not a good buy for me. I found another adapter on ebay, but a real "twin tuner". All this said, Amazon remains one of the best if not the best shopping site with confidence the Net.
