I've got a fair few of these dotted around the house and in jacket pockets / car and at relatives - they are great - to watch TV, youtube / amazon video, CCTV also while on an aircraft, in a restaurant /bar or just use to keep your smartphone on while charging.
✔︎ They fold up nice and neat - totally flat - to fit in a shirt or jacket pocket
They do send colours at random
but you can request a colour (I have) my personal favourite is the "Grey"-
Choice of colours-
Aliexpress are the Amazon of China I have purchased over 20 items in the last 12 months from Aliexpress - all good.
