What can you say?
Processing Top
Top function (does what it is supposed to reliably measure pulse)
Comfortable to wear (after 2min walk I can feel him no longer)
Only can any one recommend chest in which the electronics are removable, so you can also wash the strap !!!

Since version 4 (4.2) absolutely no problems.
