What attracted me to this video was the thumbnail, which looked like an interesting gadget, and I wanted to know what it was - but as seems to be usual for this channel, the thing on the thumbnail is not treated in the video.
I just skim through and stop when I want to see something, saves a lot of time... but also, it is way too common these days for a clickbait thumbnail to be shown and the item, product, design, etc., is not shown...I always give those thumbs down....
