Install is easy once you've done it a couple of times (unfortunately) - there are some great videos on You Tube that walk you through it. These tubes pop right in and are durable - they hold up very well! Price is fair - honestly - if you can, do it yourself! We paid a shop for our first flat tire and it cost $50 and took over a week.
