Instead of repeated question to GearBest about the quantity of Membranes in the pack, I never got the answer for it.. As the picture shows 5 membranes in the pack I ordered for it. But I received only one in the pack at the cost of $14.98. But here in India, we got membranes @ $4.75/ membrane. I was little disappointed with GearBest. If they had answered my question, I wouldn't have purchased it.
