The RRS is really nice, but given the price, I was somewhat underwhelmed by its performance. It's a work of art and I love the rounded knobs that don't snag on things, but it's not particularly smooth. I also haven't had much luck fine-tuning the resistance. I can get close, but it's not as good as I had expected. Don't get me wrong, it's a fine product, and one that serves me well, but I certainly see room for improvement.
