I bought this 20m length to use my sand blaster outside, while my compressor stays inside the garage. It is a good length for my particular purpose and the hose is of a very good quality and should last for some years. It comes coiled as in the picture and is quite stiff to un-coil and use.
This coil is best used off some sort of reel I think, due too the stiffness when new, as it really doesn't want to coil up neat and tidy after the white plastic cables have been cut off. You will also need two 1/4" FEMALE connectors to attach too the two ends so as to use it with connectors.
I highly recommend this hose for it's quality/length.
