I can't attest to ease of install because I had a bike shop do it ( they did not mention that is was a hassle).
Furthermore, I do not know how durable they are. I have about 30 miles on them and its been a good and quiet ride thus far. We'll see after 500-1000 miles or so.
Cost for both tires seems fair even if they only make it a thousand miles. But mostly got them for looks in which they don't disappoint!
