To be honest, the price-quality is just very shit, the case it comes with is amazing, but as soon as you open the case, you see an amazing looking pair of glasses, but when you grab it out of the case, you feel an pair of glasses made of plastic, paying 50eu for that + import fees + sending it back fees, i payed almost 100eu for a pair of glasses made of plastic, very dissapointed in the company made by a guy who made millions and can invest in better quality..
