I wouldn't buy another Samsung - the picture quality has been great but each updates inserts more and more adverts into the interface - including self-starting adverts. Yes if you are technical you can disable some of them but why should you have to?
Is delivery fast?
Gone up £18 since yesterday, still good price http://www.cramptonandmoore.co.uk/televisions/4k/samsung-premium-uhd/soloco-samsung-ue55mu9000-55-inch-curved-4k-ultra-hd-hdr-smart-tv.html
I went for the curved 55MU9000 from Crampton & Moore for £650. This was a £1750 tv last year and rates well. Use code FACEBOOK to drop it from £729 to £656. Can also get five year warranty for £63. I don’t care for curved TVs much but couldn’t say no for that price.
I would avoid it.
