My main need was a computer that displays speed, cadence and heart rate on one screen. This added the added benefit of eliminating the speed sensor with GPS for speed, which suits my needs perfectly. You can add a speed sensor if you want, but I don't think it's necessary and most cyclists are more interested in cadence than speed. I liked the price of this device and the quality is very good. In terms of sensor pairing, it offers BLE, also known as Smart Bluetooth. It doesn't support Ant+ devices, which is a major flaw by the manufacturer as it prevents some customers from purchasing this device. However, I was pleased that it worked with my Polar Bluetooth Smart cadence and heart sensors. As far as I know it cannot control the power meter. So if you really need it, you need to consider a more expensive device. Also, it doesn't have map navigation, so I'd suggest looking at other options if you're interested. There were some nice surprises like a switchable backlight that lets you know when you've got a call. Other features include an altimeter that provides elevation information. What I didn't like was the lack of thoughtfulness in creating the instruction manual. The instructions were short and incomplete and there really is no excuse for that. Additionally, setting parameters and navigating through sensor settings etc. via the two-button interface was cumbersome and tiresome. Why not just pass these settings to the Bryton phone app? Screen configurations are made using the phone app. So why not do all the other settings in the phone app, it would be much easier to set them up with the phone app. One final note: this review is for the Bryton 15 Neo, an upgraded model. compared to the Bryton 15 predecessor. The two main differences are that the yellow ring of the previous model is no longer present on the display and, most importantly, the two function keys are located on the back of the device instead of on the bottom bottom. It looks like they've sorted out their previous mistakes. Final thoughts are recommendations to the manufacturer to give the model a new name, don't call it the Bryton 15 Neo. Maybe call it the Bryton 16. Keeping the number 15 in the model name is confusing for both retailers and customers, and it's a strategy that lacked thought and planning. Finally, I feel like the company did a poor job of identifying the differences between the Bryton 15 and Bryton 15 Neo on their website. I think this should be fixed immediately. The device itself is a good product at a good price. I think some design changes and improved marketing and communication on the company's website will increase its market share and profitability in this competitive market.
