Fantastic tv for less than 300 notes, the M3300 series now offers HDR via HDMI as well as USB thanks to a recent firmware update.
I bought the 50" version for my bedroom when it was on offer a fortnight ago and it isn't put to shame by the Samsung KS8000 in the lounge - a tv that cost nearly 5x the price of the Hisense!
I know that lots of HUKDers have issues with AO.com but I have never had a problem with them personally.
Add the tv to the basket at 329. Go to checkout and add in the code 4K10. Job done.
