Overcart was one of the best site for those who want to buy used or refurbished goods. Probably this was the first site for exclusively for refurbished goods.
I didnt have personal experience bur my friend bought oneplus 2 from this site. It was actually amazing and looks as it was original. Only one scratch was ther on rear side which can be negotiated.
The products available were really extraordinary. All who were not affordable to buy the flagships they can buy these in overcart.
