To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
I got this at a good price when this was difficult to find at other retailers. It arrived earlier than expected which was a bonus, it covers everything that I've wanted from a heart rate monitor. The GPS tracking didn't work when I went for a run with it but was fine when I went on a walk with the walking profile active, so it might be affected with how I carried it. Saying that I'm pretty happy with it overall considering it came from the US instead of Australia
This is the second Tickr Ive purchased, the first one still works perfectly, Ive just given it to my daughter to use. Have never had any issue, always recorded my HR perfectly on my Wahoo Elemnt Bolt and Zwift.
