Light, easy to use and very secure binding system, televator (or whatever that heel lift is called) is great for long ascents and easy to put up and down with the handle of your trekking poles
Not as good of traction on steep slopes as some other snowshoes (i.e. 2010 MSR Evo Tour)
If you want light, check out Northern Lites as an alternative to these (http://www.northernlites.com/)
