A totally inferior product - not at all consistent. – Wahoo Review

When it comes to sports training, very much rests on having reliable kit and support accessory products. The last thing you want to have to deal with when psyching up for a workout after conditioning to hit a personal best is having to tinker about with a heart monitor that doesn’t work. Unfortunately the wahoo heart monitor is plagued with one problem after the next - it’s very temperamental and as and when it chooses, it either doesn’t sync with my iPhone (X10 and prior to that iPhone 8), or doesn’t see it at all; I have done everything from reload the app, to changing batteries to buying wahoo replacements - I am on my third wahoo heart rate monitor and now I am left in no doubt that it’s an entirely inferior product and a total waste of money. Not for the regular serious sportsman and definitely not for the faint-hearted. Two stars as a rating is very generous.
