If you want to buy gadgets, then please buy from an authorised dealer. But then…unless you are from China, buying any gadgets while from there is a seriously bad idea ….because you can never go back for exchange.
This was recently what happened to my friend when she bought a few power bank while visiting China…it was sold at a good deal. After buying the power bank, she tried to charge and wondered why it cannot charge.
Goodness! A fake powerbank! The casing was convincing and so was the weight. Why it was heavy was because a nice packet of sand was being packed neatly inside the powerbank.
There are also similar complaints from those who bought made in China unbranded tablet….only to find it lags, had bad screen quality and….does not support Google Play.
It is worth buying from known brands rather than dubious sellers. Please becareful.
