I purchased one such cylinder, and to my disappointment the quality is quite poor. First, despite the description, the cylinder case is not steel! it's aluminum, coated to look like steel. You can easily see this as it won't be attracted to a magnet, as well as the material is quite soft (you can carve it with a cutter if you try!) The construction of the cylinder case is poorly finished, with rough edges on the rack window (mine had a serious seam in that window, that had to be cut away - with a cutter nonetheless!). The cylinder is not skirmishable out of the box, the click-ball at the end is extremely tight, it won't move at all and therefore you cannot close the rifle. You have to open the cylinder, clear all the grease and replace it with some quality lubricant, loosen the allen screw inside the spring guide to allow the click ball to move and be able to close the rifle, and while you're there, do not forget to screw the spring guide, mine came very loose out of the box). In short: I would not recommend it, even at this price. Worst of all is trying to cheat the end-user by pretending it's a steel cylinder, while it's not.
