Signal has been good until another rider bought the same make which seems to be causing interference / erratic readings. Wrist strap broke within a week of use so had to buy a new strap. Not compatible with app to view stats. Now I've been using for a few weeks I'd recommend one which is coded and is compatible with an app but depends what you want it for. At £15 its still good as a starter.
I wanted a heart monitor that would be compatible with Strava and after a quick search this came up. And for the price it is excellent. It has a clear display and has helped me with my workouts. But unless I am being a little dumb, I cannot link it to my Strava. Which is why I gave it a 4, not a 5 star rating.
Good value, works fine.
