Strengths:    - Relaxation rate
- Huge memory meaning you can download data when you get a chance
- Brilliant software

Weaknesses:    - EXPENSIVE!
- All the s-series units are quite chunky on the wrist
- If you use the chest strap swimming, your first tumble turn will push the strap down to your waist

Bottom Line:

Excellent unit. Much easier to use than the prior generation, really like the flexibility of what information appears on the screen. R-R readings haven't really been super useful, but the relaxation rate is an excellent feature, and was a deciding point for getting it. If you're spinning up a hill at 180bpm, the relaxation rate will give you some clue as to how much 'juice' you've got to attack again. Has way more timers than I ever used, and in hindsight would be really useful for setting up structured stationary trainer workouts.
