    Fast shipping which is appreciated. Well packaged, which is also appreciated since the post office and other carriers seem to destroy every package nowadays. It doesn't matter if it's USPS, UPS or Fed X, In Florida they destroy every package they handle. Almost every package i receive is either torn open, crushed, mutilated or destroyed. This product/package arrived intact, safe and undamaged because this seller packaged it well. Got a good deal and would recommend this seller.
