Review on Muzata Invisible Swageless Protective Stainless by Keith Morris

These fittings are made from soft aluminium, so at the first sign of real force your head will curve and become illegible. And the bit that comes with it is bent, so you'll probably have to supply your own. And the special wrench you need for installation is also soft aluminum so it opens as soon as torque is felt giving you a very limited number of uses. It definitely won't take long enough to finish your railing. (Mine expired on my *second* fitting.) This is complete junk product. Don't spend money like me. Avoid Muzata products at all costs.
