Flexzilla here also. Nice product.
Pay attention to the details because Flexzilla supplies hoses with 1/4" and 3/8" npt ends. I got mine at Tractor Supply.
PS
Don't tell anyone, but I use one of their 100' garden hoses to extend my airlines. It's rated for 150 psi and the end fittings are the same quality. Zero pressure drop at 100' with that hose.
