Strengths: Looks like a watch, much better than than the 201. Satellite pick up excellent and available software is excellent for training records.
Weaknesses: People with thin wrists may struggle to wear this comfortably.
Overall: Training on my own I am often losing 2 minutes a mile on my race times. This watch enable me to keep track of my pace and pick it up or slow it down as required. How did i cope before hand? I prefer this to the 201, but people with thin wrists may prefer the old style to this. Price varies a great deal from retailer to retailer so shop around - but an excellent buy if, like me, you train on your own.
