I personally own two made from them and they are nice! You can not beat these prices, I am going to order up two more.Trust me when I tell you to jump on the deals because they sell out quick (at least last sales they did). Snatch them up fellas,if not for yourself,they make very nice trade bait,and the quality is unbelievable for the price...
