Strengths: Large clear display, many functions, accurate, robust, altimeter resolution of 5m.
Weaknesses: Price?
Overall: Been using it for 6 months without any problems. Find it really useful for navigation to know my altititude and it's nice to that it has so many useful functions for accumulated altitude gained, highest point reached, rate climbed per minute etc. (if you're into that sort of thing).
Weaknesses: Even for 1.5 it's too wide to be fast (the contact area with the road is very wide causing lots of lateral movement that is more consistent with an MTB tire than a road tire). Still prone to punctures.
Overall: For a faster road tire offering just as much puncture resistance I prefer a narrower tire such as a Tioga City Slicker 26*1.25/1.5 or Panaracer Pasela 26*1.25.
Strengths: Light weight, pretty robust in all types of conditions, holds air well.
Weaknesses: Pinch punctures and a little expensive (check web for suppliers offer sale prices)!
Overall: I never ride without them. Sure I've had pinch punctures and slow very sharp pine needle punctures, but these are few and far between. Once I got home with a 1cm split in my tyre but the tube was ok.
