Average quality !!
I bought two pieces, best price for stainless steel exterior ... cylinder quality it's good , the front stainless steel, the back are quality aluminum, Interior are average in quality rack similar in quality as Vanaras the only big minus is the head of the piston which is painted aluminum, you give the impression of being in polymer ... should be serviced before use, are poorly lubricants and poorly adjusted ... rack is not bonded to the piston , seals are good ... O-ring on the piston end is a little too soft
