For anybody that owns a Samsung 4K TV and is wondering whether or not to purchase this accessory, wonder no more! This nifty little unit is easy as can be to plug and play with ZERO problems at all. Just make sure to plug the unit into the HDD USB jack and select "UHD Video Pack" as your source on the SmartHub. It really is that simple. Contrary to what I read in other reviews here, the content is absolutely 100% 4K UHD; NOT simply an upscaling. We have a 2016 70" Samsung 4K UHD TV (UN70KU6300), and for those that complained about the quality (UHD-vs-DVD; etc.,) my guess is that they did not plug their unit into the HDD USB jack. If they had, it is crystal-clear that every title pre-loaded onto this external storage unit is, indeed, UHD.Others have mentioned that they would never pay for this accessory since it was given away with purchase for select Samsung 4K UHD televisions in the past. While that might very well be the case, that would have been in 2014, when the price of a 4K UHD television was a whole lot more than it is now! Given the choice, I would rather pay what I paid for our TV in 2016 along with the $38 paid for this UHD Video Pack any day given the difference in price and technology then and now. On that note, the instruction manual included with the unit states that it is only compatible with 2014 Samsung UHD TVs, that is obviously not the case. It works just fine for us.Given not only the capability for additional UHD storage, but the titles and the quality of the titles included with this unit, I would recommend this UHD Video Pack to anyone that owns a Samsung UHD television. We are more than happy with this purchase, and I hope this helps anyone thinking about nabbing one of these while they're still readily available.
