Dont use it.
I truly want to say that I had bough 2 pairs of lens from this site but I got defective ones.
there are lots of disadvantage of using this site-
1.cost is relatively high.
2.glass are not so cool.
3.takes relatively long time for deliver.
4.u might have fixed the spring of product after receiving.
so I dont refer for using this site.
or go to showroom near you.
THANKYOU.
