Strengths: feel very light weight despite the RW review - feet do feel comfortable from temperature point of view (in the cold only just now)
Weaknesses: slighltly slip inside but think is due to one of my feet being smaller but tightening lace up solved - would agree re colour - one grass race in so now a bit dirty
Overall: do enjoy them and are as good if not better than the hurriane - value tempered by Wiggle's £20 or so discount and free t-shirt - would not pay the RRP
Strengths: ease of use, quick set-up, fairly accurate over distance
Weaknesses: occasionaly loses signal so you get a speed up message (as is saying zero) then slow down. sometimes struggles to find canary wharf - worrying with all the planes flying to city airport!
Overall: excellent aid and can assist whether doing heart rate, distance or pace training - I now can understand better what I can (or can't do)
