Big thumbs up for the M400 - I purchased mine in early Jan when the battery failed on my garmin.
Its really easy to use and the iphone Ap is easy to navigate. I like the fact that I can wear it all the time and use it as a daily activity tracker (bit like a fitbit) but also use it as a training monitor while running. The heart rate monitor is on a soft strap that is more comfortable than the Garmin one, so I've used it more... Definatley very pleased that I bought it.
