Cardiosport Heart Rate Monitor Armband, Bluetooth ANT+ for running, cycling, gym. Compatible with Strava Zwift Peloton Garmin Wahoo App

I bought this following heart surgery, to keep track of my heart rate whilst going through cardiac rehab.I found that my sports watch was wildly inaccurate, at times, and just too unreliable.For the price, this does everything I need! It's compatible with several different apps, and is very comfortable to wear for prolonged periods.This one actually fits around the forearm very well and is easy to fit. There is just enough stretch in the band so you can snug it up, if you like.It charges up quickly and gives impressive battery life. As said earlier, it is compatible with several brand apps. I used it with Polar Beat, and have no issues at all pairing up.Great value heart rate monitor that isn't overly expensive and works great!

Comfortable, super easy operation. Good clear colour coded indicators. Quick and simple, can be used with various fitness apps but equally as good as a stand alone.

Ordered this to use as the heart rate monitor for my rowing machine. It works really well with the Concept 2 interface and very comfortable to wear.Definitely recommend

Received this item in good time. Works well with my Peloton Bike. Easy to use and comfortable to wear. Highly recommended.

The Cardiosport Optic is a lightweight pulse monitor that supports Ant+ to work with gym equipment and Bluetooth to work with your phone or smartwatch. It isn’t a watch, and it isn’t smart. It measures your pulse accurately; and has a single LED to give you what band your pulse is in bands - Blue, Green, Yellow, Purple and Red.Blue is normal pulse; red means slow down! If you make it into red, there is a vibrating alert to warn you if you are overdoing it.The Optic is lightweight and has a comfortable, easy to wash, Velcro strap. The strap is long enough you can wear it on your wrist or bicep (there are two anchor points to help adjust it as needed.) The monitor is IP67 sealed; you can shower in it but not swim.It charges up very quickly using a usb-a (which lost the star) to two pin charge port on the back of the monitor. When charged the LED on the front glows green. It worked with the rowing machines and treadmill in my building’s gym, relaying my pulse to them without me doing anything.I was also able to pair it to my phone; and use it to track walks and runs. Cardiosport don’t have their own app; so, I used Polar Beat which was excellent for tracking my workouts. This is a downside for me; if you want to track your run you need to take your phone with you.The pulse monitoring is great especially in the gym; if you are wanting to use it when you go for a run outside; needing to take your phone feels like a step backwards after using a smartwatch. In the gym I am not sure how it worked; maybe holding the handles as it started paired it to the treadmill; but it did – as my pulse went up and the colour went yellow the treadmill screen was displaying numbers in the 130s.

For our friends son, extremely important, which I why I gave him this. He is a runner and keep fit fanatic and always checks his vitals each day. Having this fitted to his upper arm whilst running has already helped as he now knows all is well in the heart department.He's happy with it and he says it represents good value for money - who am I to argue.I am happy to recommend this.
