I do not recomend anyone to buy used products. Ask yourself a question, under what circumstances you will sell your mobile or any other product? The answer is very simple- when you found some defects or issue, only then you will take the step to sell it. A year ago I bought a mobile handset and later found that it is defective and most of its original parts has been replaced with cheaper or duplicate parts. Olx is only suitable for selling products but not worth buying any products.So dont choose to buy used products and I don’t see any good reason to go for a used product.
