I would say that the grade below consumer grade is “functional prop” grade. There’s a type of consumer electronics available on Wish/AliExpress/etc., which is designed for people who want to appear at a glance to be using a certain expensive device, for status-signalling reasons. The devices only have to be real enough to allow you to pretend to be using them without drawing suspicion, and only have to be rugged enough to last until the device being mimicked isn’t fashionable to have any more (at which point you get a new knock-off aping the new cool thing.) Surprisingly, these devices do work! They wouldn't be convincing otherwise. (How can you seem to be using the best new phone if you have to pull out a different phone to check your text messages? How can you seem to be playing a Switch or a PS4 if it doesn't turn on and show pictures and sound on the screen/a TV?) It's just that they work as terribly as you can imagine, given that costs are optimized to meet the minimum needs of someone playing pretend and no more.
