Works like a dream. Both Bluetooth and ANT
Used for 3 to 6 months
Absolutely love this product. I can have my phone strava (Galaxy Note 8) connected via Bluetooth, along with my Garmin Edge 500 via ANT BOTH at the SAME TIME. Connection is a breeze. Battery life seems a bit less than my old Garmin HRM chest strap, but since it can run two transmitters at the same time, I can accept shorter battery life. Exceptional value.... and AMAZING to have 2 year guarantee for peace of mind for quality and durability.
Good value
Used for 3 to 6 months
A great little unit. It’s works well with my phone. Decathlon’s software isn’t that great, but this works well with other apps.
fenix 3
Used for 3 to 6 months
worked with suunto/bryton but I cannot get it to connect to fenix 3 which is a real disappointment!
Great value. Simple to use
Used for 2 to 8 weeks
Paired with strava on my iPhone without problem, worked without problem for the last 2 weeks.
false claims
Used for 1 week or less
Claims to be compatible with Runkeeper on Android but Runkeeper will not detect it. Decathlon utility app also says my phone is suitable
doesn't connect to Garmin 810
Used for 1 week or less
Tried to connect via Ant to my Garmin 810 - device not found. Tried to connect about 50 times in all then gave up. Reading the reviews it's either the battery that's dead (quite likely as it's already installed which seems really stupid as its likely to lose charge this way). Ordered online for Christmas off my wife so now got to package it up, get her to email me the receipt, get my daughter to print it off for me at her works, traipse all the way to Decathlon in town for a replacement/refund....... or...... chuck the pile of crap into my cycling junk box along with all other manner of equally crap electrical gadgets and forget all about it !!
Heart rate loud reading
Used for 1 week or less
Does this device linked with strava or Decathlon app tells you (voice message) your heart rate every XXX km? ... Like strava does with pace per km
It's good ..
Used for 2 to 8 weeks
It's good works and pairs easier than more expensive types works well , first battery didn't last long but probally my fault as left it on strap. So far so good , and for the price awesome .
Cheap, easy, and it works.

My old Bluetooth HRM died and I wanted a replacement mainly to use at my local gym. This was so cheap I thought I would give it a go even though I wasn't sure it would be compatible. It works like a charm on the Technogym Excite 1000 treadmill in bluetooth mode. It works flawlessly on the Star Trac Spinner NXT bikes with the Spinning Studio Computer in ANT+ mode. It also works perfectly with the SportsTrackLive Android app I use on my LG G3 phone. The only thing that threw me initially is that with these new Bluetooth Smart BLE devices, you don't pair them, they just work directly with the app. It really doesn't get any easier than this.
Useful when it works...
Used for 2 to 8 weeks
Not easy to get apps/devices to recognise it, even when previously connected. May not be the fault of the monitor, but very frustrating none the less.
