I purchased this as a replacement for my aging Cobra. I LOVE the Zulu! First, it may not seem that important but it is VERY intuitive. Displaying that much data on that small of an area requires a ton of consideration. My wife has an i450T and the zulu seems easier to use. Second, it TRULY is sized correct to wear as a full time watch if you want. I won't wear mine daily but on vacation, you bet I will! The only reason I wouldn't wear it daily is that I would be afraid of damaging the face. Suunto has always made great products and if you can stomach the price, the D6i Novo Zulu is the bomb!
