Canon EOS System - EF 1.4 Extender II
Canon EF 1.4x II Tele-Extender

Canon Extender EF 1.4X II - Telephoto Extender: The latest telephoto extender designed to work with Canon EOS cameras and and specific telephoto and zoom lenses.
Installation and removal is easy. Using the 1.4x will make the 70-200mm into a 98-280mm lens. There is a loss of one f-stop (so an f/2.8 lens becomes an f/4 and the 70-200 f/4 becomes an f/5.6). For outdoor sports or racing photography this is not really noticeable.
I did not receive the extender in time to use it at the track during my last photo shoot but I look forward to using it next season and will post a field review at that time.
