Looks like quality equipment, so far so good. It was a bit difficult to remove the old blocks even though they hadn't been changed for so long. I hope these last a lot longer, they seem to be well built. I was a little apprehensive about the installation as they seem to make it clear that damage during installation is not covered although I think you would have to do something pretty crazy to damage it. Didn't realize they sent a simple laser cut ring to add support to attach them until just before installation, it really gives confidence. This isn't an easy project though, make sure you have a decent setup to install it. They make all kinds of kits and you never seem to have enough options as far as mugs etc go. I read another review that said the connections were very tight once installed. If I were her I would be concerned because mine were very slippery. clearly noticeable in comparison to Moog's nylon modules. It actually creates a slightly different driving experience as you get more road feel. It's kind of crazy money, so better hold it. I will update my review if I ever run into any issues. I have about 1k km so far.
