I had purchased a "mystery box" voucher for $12 from KGBdeals.com for products that were supposed to be worth $150. Instead I received Chinese fraudulent cell phone accessories that can be bought on eBay for $3-5! Additionally, it took almost 3 months to ship the product instead of promised 2 weeks. I'm afraid even to use this stuff as not to break my cell phone. DON"T BUY FROM THEM!
