Absolutely horrible customer service! Buyer beware! I have wasted so much time trying to get a refund on the infrared masks… and the just keep sending me some vanilla response by a robot! It’s ridiculous! I’m am so cross! The products were not cheap and they can’t tell me where the products are, when they will be sent, they don’t come back to any of my emails about a refund! Do not buy from this company! They are shit!
