fake scam to prey on those who dont know
you can find the same thing under any brand

an example review
https://www.youtube.com/watch?v=j71M-Qy2Nbc

they have ancient old tech, like mediatek mt6580 processor which only supports 3G
the ram/storage is faked and will show like 1tb but once you download stuff it will say you used a lot
the android version is also faked

simply avoid and dont buy

for the reviews, at least on shopee i've seen how they do it
they set the product to a low price, like 10 cents
have a few accounts buy like 100 of them
leave 5 star review saying it is very good
(sometimes they even steal pics from real product reviews)

so, at a glance from outside
1k sold, 5stars

if one shop gets taken down another 3 will pop up the next day
