Worked great after quick sync…..great price too!
Loved the blinking red light to indicate use. Added to my Geoid CC600 with ease. No problems….added it the CC600 faster than my Garmin Edge 520 plus and it has worked great on two rides so far!

Expremely Happy!
This is a great product to use to measure your heartbeat. It is super easy to set up and I love it!

Worked fine at first, then quickly failed
Had to replace the battery after <3 months, and it just provides random data ever since. It will show a variable heart rate while sitting on a table... Terminals already show corrosion too. Cheap product, guess I got what I paid for.

Update:..This HR is not accurate reads waaaay to high
“This HR is not accurate reads waaaay to high.” -Is my original post with the vid.Update: the monitor worked great for a few months and as my video says … It’s been reading very high .Geoid responded immediately with refunding me for the faulty item extremely fast!!Die to this great customer service I’ve purchased a second one. Ive used it and it works great right out of the box . So we’ll see how it does moving forward. If I have any issues I’ll connect with Geoid.I’ve changed my rating to a 4 star. Customer svc is great. Obviously this is an excellent value. Hopefully it lasts us for quite a while ..

Amazing heart monitor that bears with several types of computers
I bought this heart monitor to pair with my Garmin computer and it works beautifully. I also pair these monitor with my GEO ID computer and works flawlessly. I do highly recommend this heart monitor.

Ant+ Great Bluetooth Not So Much
First off I have never had a great experience with chest strap heart monitors. I have gone through 4 in 6 years. 3 of them expensive well known brands. So Im done paying for expensive HR monitors that last a little more than a year.This one works so far, and seems accurate. The major issue is in Bluetooth—it intermittently goes blank. And it doesnt seem to be a random phase, but every 10s or so (see attached image). In Ant+ pairing it works as expected.At $20, if I get a year out of this HR Monitor, I will be happy. I also like that it has a light, so at least I know the battery is good and you’re not aimlessly swapping batteries out.

Connecté à un garmin 530, fonctionne parfaitement.Mise à jour commentaire après quelques mois d’utilisation pas intensive : comme d’autres utilisateurs, la précision s’est dégradé, c’est désormais n’importe quoi, passe de la mort à 180 pulsations, rien n’y fait. Prix intéressant, mais à l’heure d’utilisation, ce n’est pas du tout une affaire.

Ero scettico dopo aver utilizzato una fascia polar. Devo dire che al momento va molto ad un prezzo molto competitivo.Consiglio

Es detectado enseguida y se vincula rápidamente con el dispositivo iGPSPORT BSC100S, de otra marca. Sencillo de acoplar a la cinta elástica que es muy cómoda y se puede lavar sin el sensor acoplado para que no se estropee. Lleva la pila incorporada. La única pega es que cuesta mucho abrir el alojamiento de la pila y parece que el plástico es muy blando y no va a aguantar mucho abrirlo y cerrarlo con una moneda, así que espero que la pila dure mucho.
