Sigma ROX 4.0

Easy to install. Great readable display, always rechargeable. Navigation is limited but for that money it is a fine device and if you use the navigation in conjunction with a phone, it works fine. Sometimes it is difficult to click the computer wash. When using for the first time, try practising clicking on soft ground for a while if device slips then it falls softly. Click system with magnet would be more convenient. Once it is attached, it is firmly attached.

Pros & Cons

I bought it as an entry-level model to gauge to what extent a bike computer would add value and which functions are really necessary. After a while, it became clear what was missing for me personally. But it is a great starter model that nicely displays your performance and can introduce you to the data that comes into play during a bike ride.

Pros & Cons

nice product easy to use and good price/quality ratio

Pros & Cons

Very nice device, screen layout customisable. Lighting automatic, in the dark just read your display, battery life very long, I use it purely for speed, distance, time, temperature...all in 1 display.

Pros & Cons

Very practical that you can customise the layout to your own preference. I'm a fan.

Pros & Cons

The product looks good and solid, easy buttons , big screen. for me the purchase was because I wanted to pair it with komoot (especially the point to point nav. Unfortunately this is not possible with my phone (huawei mate 20 lite) so the whole system does not work anymore to use point to point navigation too bad this cannot be done in their own app (sigma ride) after contacted komoot and with sigma the product has been sent back, they cannot/will not solve it. easy to say that your equipment (my phone) maybe they should have put more effort as my phone is suitable for all conditions in this...

Pros & Cons

Display is easy to see and easy to adjust. The app is a disaster, almost impossible to connect. I just sent it back. If you don't believe me take a look at the reviews of the app.
