Here is one good review on aliexpress.com:
I’ve purchased some items from aliexpress and got all the items without any issue.
I only buy the items with the following conditions:
The item with price less than $20.
If it is not available in India.
If it is available, than the price should be less than 50%.
The seller must have more than 200 +reviews on that item.
When I order the item, they send a tracking number within 4 days and you can track it in china post mail tracking system after 10 days (Don’t know the reason of 10 days to update in the system). Just wait 15 more days, so you can track it in India post tracking system.
Be careful for the length and size of the product as they produce in mass for the International market.
Forget about the return policy of aliexpress. To get a product it takes around 30-50 days, so you can imagine how much time it will take to return and get the refund (I don’t have any return exp.).
My opinion:
It’s always better to go local market, see it in eyes, check it and buy it. It may cost 10-20% more. Otherwise buy it from Indian shopping web portals by cash on delivery option and the delivery time is too less.
