Review: Reliable and constantly connected - Works brilliantly. Cannot fault it at all. Unlike the couple of reviews that are negative about the device and its compatibility with certain apps, it has been known for quite some time that a lot of apps are moving away from permitting third party devices work with them or require you to have a paid subscription to be able to do so, Strava one of these. So bearing this in mind blame the app developers and check before hand. That said I have Strava premium account so no loss for me and it works a treat. Set up, once the fiddly part has been done, using the supplied fixing kit, getting the sensor fitted to the back wheel and paired with my phone is straight forward just like their heart rate monitor that I also use which I can say has been absolutely spot on so far. Can't fault this process at all for either device. Simple as one two three. In use as speed or cadence sensing, I have found the sensor to be just as good as various other premium-priced devices that I have used in the passed. No loss of connections, no bad syncs, no errors at all from my experience so far. Switching between the two modes does require the fiddly part of unclipping from the rear hub and placing replacing the battery but that is nothing, most of the time its fitted and stays put but on some days I will fit the sensor to the crank arm for use on the bike trainer and use the cadence features. No issues with speed or cadence pickup. Given the fact it's on one unit and no magnetic counterpart switching between the two is an acceptable part of such dual usage. To get working you just need to power up your app and Bluetooth and rotate the crank or wheel and the pairing will be instantaneous. Definitely a good device for those looking for a cadence or speed sensor with good reliability but on a budget.
Review: Cheap, effective and simple to use, but mode changing is a farce. - I bought these as Ive recently purchased a set of rollers for my bike when Im warming up for cycle races and wanted to record data while warming up. They work absolutely great, however 2 issues I have with them, the elastic hoops you get with them that secure them to the hub of the wheel or the crank arm are too big. When I fitted the Speed sensor to my front hub, it would move slightly while rotating so I had to add a zip tie to hold it in place. Other issue is the changing of modes. Each unit is identical and the only way to change it from reading speed to reading cadence is to remove the battery and place it back in again. This is a joke and inconvenient at best.

## Features

- [Battery] Remove the insulating sheet of the pre-installed battery before usage; re-install the battery to switch between the speed and cadence mode.
- [Mode] 1 sensor can ONLY select one mode (Speed or Cadence) at the one time.So you need 2 sensors to test both speed and cadence.(1 for speed,1 for cadence)
- [Device] When using the Bluetooth protocol 1 sensor can ONLY connect to 1 APP or device concurrently; When using ANT+ protocol it can be connected to multiple devices at the same time.
- [Connection] When using a smart phone APP, you need to search for the sensor in the APP, searching through the phone system’s Bluetooth setting is invalid.
- [Hibernation] S3+ sensor will automatically enter the sleep state for 1 minute to save power after the sensor is stationary, the sensor will ONLY start sending broadcasts after it is properly woken-up.

## Questions & Answers

**Q: Will this work on a spin bike?**
A: Mine is a spin bike I have it on the hub

**Q: Does this work with the PlayStation vr vir game**
A: No

**Q: For Garmin, which metrics does it transmit in addition to speed and cadence? Does it provide distance? Thanks.**
A: Purchased for use on a bicycle/turbo trainer. The sensors transmit only speed/cadence. Connected to an iPad via Bluetooth, various apps calculate power and distance from the speed/cadence information. 

I would expect the same would be true for a Garmin app or device. 

Hope that helps

**Q: Can the cadence mode but used for an indoor bike by attaching to a shoe or inside the top of a sock?**
A: Yes it can be used this way but it's designed to be attached to the crank arm (I put it near the pedal on the left crank arm), this is how I use it on my indoor trainer.
