Good HRM with extras
Bought for Zwifting, but the range seems a bit on the lower side, not sure if its just the Apple TV. Otherwise a solid HRM with the additional bridging capabilities.

Pros & Cons
5 / 5
Accurate, comfortable and functional
It is as accurate as they claim, and easily finds my heart rate. It is a very comfortable strap, and has no problems connecting to Bluetooth or ANT+.

A Zwift essential.
Bought this HR monitor to use as a bridge for bluetooth devices. Allows quick and easy connection of all of your bike sensors in an Apple TV 4k setup.

Great HR Monitor, especially for Zwift
Easy setup, great upgrade after my old Garmin HRM. ANT bridging makes Zwift connectivity very simple and bulletproof against signal drop-outs. 4iiii app is not as fancy as the competitors' apps, however does the job adequately.

Great heart rate monitor
With the Wahoo Tickr no longer available anywhere, I went for this one from 4iiii. After discounting at Mantel, the price difference was only a few euros. The heart rate monitor performs well, in my opinion even slightly better than the Tickr. It consistently records my heart rate from the start of the ride, whereas the Tickr only started to work properly with a little sweat. In addition, the 4iiii seems to communicate with my cycling computer (ELEMNT Bolt) a bit more frequently. All in all, a good purchase.

Fine heart rate sensor.
Fine heart rate sensor. Sits comfortably around the chest and accurately measures heart rate.

Excellent heart rate belt
Meanwhile used on the road and on Zwift. Quick trouble-free connection with Edge and the indoor trainer. Data transmitted seems very accurate. You forget you have the strap on. Top so, happy with it :-)

Absolutely reliable HF sensor
Bought the sensor mainly for the bridge function to use all sensors (Ant+ and Bt) with Zwift on the Apple TV. Outdoors, I tended to use mine for RF measurement. Setup went smoothly and the connection is absolutely stable so that I now also use the RF sensor outdoors.
Pros & Cons
5 / 5
Super Easy
Super simple configuration and ingeniously suitable as a BLE bridge for twinning via AppleTV.
Pros & Cons
5 / 5
Top HR band.
Bridge is especially handy for indoor Zwift sessions. Furthermore, the unit also fits the old wahoo band, handy. Fit perfect, no fiddling with pairing. I haven't looked at the fit-logging yet.

Very good conversion of Ant+ data to BT
I bought the heart rate belt to record the Ant+ of my home trainer (IC5) and then forward it with the measured heart rate to my Apple devices via Bluetooth. This allows me to use Zwift perfectly (Apple TV and iPad).

Very good!
Hey! Very fast delivery and worked to zwift with no problems right away.

Great product!!!
Use as a bt bridge, super convenient!
5 / 5
Just right
Pair once with the app and then it works well and pairs quickly. Top when you use Apple TV with gliding and an ANT+ cadence sensor. Only use the phone's Bluetooth for "earbuds". Less problems with Discord and less power drops.

Perfect for Zwift

In combination with Wahoo and AppleTV a perfect part
After initial difficulties (operator), the chest strap does its job perfectly and replaces all sensors. Super when twinning
Pros & Cons
5 / 5
The perfect heart rate belt
Having tried many brands, from Garmin to Polar, this is the best band so far. It seems much more accurate to me and is also quickly found by all devices. Ideal for Zwift in combination with Apple TV. The band itself feels nice and the front closure is also very nice. In short, this band is well worth its money.
Pros & Cons
5 / 5
Easy way to connect old ant+ devices to newer apps via Bluetooth.
Solves the transfer from ant+ to bluetooth so I can use my old cycletrainer with Rouvi and other apps, it also transmits HR together with the ant+ data.

Great heart rate monitor and easy to pair with zwift
5 / 5
excellent HRM
Fine HRM. plug and play pairing, only I find the attachment not so optimal as it has to be clicked on and off all the time. Have a separate strap on which the HRM is permanently attached and which just has to be done around the chest with a clip

Multifunctional heart rate monitor works flawlessly
It works great to use ANT+ and send it to iOS devices with BLE. I personally use Bodybike and Zwift on my iPad, where the chest strap handles the communication between the bike and the iPad.
Pros & Cons
4 / 5
Top to expand your limited number of connections with Apple TV
I use it as a bridge for an extra Bluetooth channel for Zwift on Apple TV. With the app, you can get that done in no time. No drop-outs so far.
Pros & Cons
4 / 5
Does what it needs to do
After the seal on my Garmin heart rate monitor failed for the umpteenth time, I bought this heart rate monitor. It uses the old way of sealing at Garmin. This system is much better than the screws on current Garmin heart rate monitors. Sometimes an unrealistic value is transmitted for a few seconds but due to the fact that this is only the case for a very short time, it gives little influence on the average heart rate of a workout.

Precies
Eerder review geschreven dat ik niet happy was. Nu na update Zwift/ Apple TV tevreden. In tussentijd ook Tickr geprobeerd maar Viiiiva consistenter.

Does what it should but is difficult to work with the app, etc.
After much trial and error, I got it to work as an ant+bridge for the phone.

Does it all!
One sensor does it all: BLE, Ant+, HR! Comfortable and reliable.
Pros & Cons

Hmmm, not happy.
Had a love/hate relationship with this HRM from the start. Owned it now for a little over two years. I bought it because of the bridge which I now no longer need. My big problem is that the battery runs out quickly and the HRM is frequently untraceable (via BT) or drops out. I have another HRM (ANT+) which always works perfectly. Maybe I just had an inferior one.

Accurate sensor but very poor quality strap. Product unusable without strap !!!!!
Very accurate sensor, easy to connect. But one big problem. The strap (belt) tore and became unusable after less than 10 hours of use.

bad at zwift
firstly that there are still no zwift maps, bought tacx in October so don't have a working zwift now, secondly: with zwift the 4iii is not always recognised and I just went back to my garmin strap

problem with app
I have owned the heart rate monitor for about a month now. From the beginning, I could not download my data to the viiiva app. Contacted at mantle and they told me to contact at viiiva. 1st mail, I had to reset the heart rate monitor and reinstall everything 2nd mail ( had this in reply) This has been confirmed as a bug with our app and Android 11 that affects file storage. We will be implementing an app fix in the next update due to be released in the next couple of weeks. Please keep an eye out for this update to resolve the issue. If possible, try to download via an older generation Android or iOS phne. viiiva always responds quickly to your emails. A disappointment in the app that this takes about 2 months to resolve. The heart rate monitor works well. A good communication with garmin.

don't start.
from the beginning a lot of connection problems. rpm combo with heart rate, which i bought it for, does not work. The app no longer finds the heart rate monitor, and now my phone and wahoo Kickr don't either.

Nice belt but poor data quality (dropouts and spikes)
Unfortunately there were data errors in 5 out of the first 6 workouts I tried (either HR dropouts or HR spikes), despite following the instructions carefully, and once it had failed the first time, I tried: super-wetting the band, using electrode glue, rotating the box partway to the side, changing tshirt, changing sportsbra, and any other tricks I've learned that may apparently help to eliminate such things. Sadly I won't be using this product again.
