Zetronix Problem: I ordered a smart glasses from this company, while I was ordering the product online, I instructed that If product is used or opened box, I would returne it back to them, so when I received the glasses, very quickly find out it was used, and they even didn't bother to wrap it up properly, it was dirty items inside the box as well as and damage hard case, I called and emailed them few times but no response at all, few hours later I shipped the product back to them, after they found out that I returned it, they sent me an email stating there would be 15% return fee and That I should read terms and conditions, I tried to explain that on their website with big words posted that 30 days return gurantee with no restrictions applied anywhere around it, but they didn't care and worst than that they won't refund me for 15 days, these people lied, mislead and sent a used product as new, Boston Massachusetts
