Perfect no problems via the Fire Stick

This isn't running Android TV unlike most of Sony's TVs, so no sideloading.

I have and works fine!

i hear yah,but i so want to pull the trigger on this,but got something else in mind

​yes, just take it back. or buy it, and return it with yesterday's receipt?

Talk to them on their facebook page

I bought an Xperia Z3 Mini Tablet from them and it dropped £100 3 days later so I asked if I could have the difference refunded (to save me returning it and then just buying it again)

They conceded and gave me the difference.

I bougt a printer a couple of years ago from Argos, the following day it was half price..... So I returned it under their 30 day rule and got my money back. While the assistant was competing the paperwork I casually asked if they had any of the half price units in stock.....

With a perfectly straight face he said there were none of the unopened units in the storeroom, but he understood there may be an open box customer return becoming available very shortly, was I interested?

He rang the transaction through and I took the original box home again!

Not relevent, there's no local dimming or wide colour gamut.
