put this on my wish list right before Christmas and , ta-da ! find it under the tree not long after . have only have it a short while , but like what I see . probably one of the biggest factor with it would be the size\/weight ratio . have a steel or even plastic toolbox this size present challenge if you want portability . the material seem really tough , but give you the ability to carry it around -lrb- obviously depend on what be inside -rrb- . the exterior level carry loop give I a easily accessible place to put my 2 foot level , so that be a bonus . look forward to a long work life out of this .
