I recently puchased one of these 50' hoses for my new DeWalt twin tank air compressor.  This is by far the best 50' hose on the market today without question.  It remains totally flexible in cold temperatures unlike those vinyl coiled hoses on the market.  It also lays flat when in use and does not coil up in places.  You don't have to worry about tripping over this hose.  The couplings at each end of the hose are very high quality and the yellow color is very noticeable to keep others from snagging the hose and tripping on it.  The 50' lenght is perfect to allow you to move about freely and not relocate your compressor often.  This is a great product and the price is right.  Get one of these.  You will be glad you did.
