@mykepredko ‘high accuracy’ says the marketeer. What is high accuracy asks the engineer. … 
You can’t be accurate if it isn’t repeatable, putting the same object on a scale over and over it needs to be very similar. The junky kitchen scale I bought varied by 7 gm when a ten gm weight was added sometimes it would be 4 sometimes 14. Laughable, useless even for baking.
It looks good but so does my cousin’s old Porsche kit car. It looks fast, but the VW bug underneath wasn’t.
Let hope the Creality is at least repeatabl-ish.
I know the importance of accuracy AND repeatability - I was responding to your comment about accuracy.
My $4 Dollarama scale is extremely repeatable and accurate - to the gram level as far as I can tell with no surprises when putting on off a load including putting it over different spots on the scale surface.
The point is that you can get a good quality scale (accuracy and repeatability) in a cheap package. I have no reason to think that the Creality product won’t be as good as something you can buy in a dollar store.
I think the usability is the major concern especially when it come to understanding the empty weight of the spool and how that affects the displayed value.
EDITED: I wrote this in my daughter’s orthodontist’s office on my phone and I could have done better.
It could be as accurate but maybe not. Everything that comes out of China is a crap shoot. Maybe good, maybe not.
I use lab grade scales many times a week. I think I am using a different standard. My go to scale is 3500gm-0.01gm range it is accurate to 0.05 up or down. I it is a challenge for me to accept a scale that is +/- 1-5 gm. In reality for this application a few grams up or down and repeatability of a gram or two is likely all that is needed. 5-10 gms of filament will not make any difference.
I need a good bench scale at home for my platinum printing. It is way over kill for measuring filaments rolls. Ridiculously in fact.
