This company has extremely poor operations. I cancelled the first order I made w/ them in 5/2018, because they never informed me that the lens could not ship because they were out of stock yet they billed my acct, Also they could not tell me when the lens would be available to ship. 1. No inventory control 2. Noone follows through to resolve problems 3. Phony platitudes of service but nothing gets fixed. 4. No record of previous conversations with other reps or customer 5. Disorganized-Rx uploaded and faxed several times but I received the same stock email that my Rx was not on record. 6. no communication w/ customers to clear up issues. order drops in a black hole.
