Don't buy from these folks, Cheap junk and fail to send after the first shipment. No response to emails.
I was so disappointed by this subscription and now re-reading the reviews I see that I am not the only one this has happened to... I paid for 3 months up-front, it took forever for me to receive the first shipment and then nothing ever came again. I tried contacting the seller but after a month I still have not received a response nor a refund. Unfortunately, I wasted my money as I paid for 3 pairs and only received one. Save your money and shop elsewhere!
If there was a negative star rating system, you would receive 5! Customer service is none existent and they have not sent anything! So folks if you want to subscribe to pure failure, this is the place for you! Absolutely the worst ever! Plus I was forced to give them at least one star, in order for my review to even been submitted!!!
