FNIRSI-1013D "100MHz" tablet oscilloscope

Valentin:
Hello dear people! I was roaming around aliexpress, like one does, looking for cheap equipment and I stumbled across this thing for ~$140 which is really cheap when considering what it's specs state(which I don't really believe after looking at the mini scope's review), looks very new tho and I haven't been able to find any videos or even posts of it anywhere.
So I was wondering I'd come on here and ask you wonderful people if it might be worth buying, or if maybe someone has their hands on this thing. I don't have a scope in my lab yet and I was wondering what I should buy.
I was looking at analog scopes but prices here are absolutely outrageous(150 euros for a used 1 channel 10mhz analog scope, give me a break...), I found some better ones like a 25MHz 2 channel Phillips for 100eu, but for that price, I'd rather use a Chinese USB o-scope with 60Mhz bandwidth, but even then I'd rather use a propper bench scope, so this scope might be something of value.

Here's the listing:

I can't find the exact FNIRSI-1013D 100MHz tablet oscilloscope, your link doesn't work.
Dave's looked at the yellow FNIRSI-5012H 100MHz bandwidth 500MS/s. :popcorn:

Yes, I know he looked at that, that's what I mentioned in parenthesies.

Weird. I clicked it and it worked, let me link another one. This one should also be from the official firnis store on ali:
