I have ordered several times from EZContacts and have been happy with the contacts and their service each time. I had previously ordered from another company and unfortuately found several of the contacts to be unusable. This has rarely happened with the contacts sent be EZContact and on the few ocations it did, it might have been user error. The reason for the 4 vs. 5 star rating is because the free postage is not offered when a promotional/coupon price is offered, which doesn't seem to be clearly stated. That made it a little challenging to figure out when trying to place my order and a postage price kept showing up. Over all this seems to be very good company.
