In practice, the ThirdEye works well. Both on the highway at higher speeds and at lower speeds in built-up areas, vehicles behind my motorcycle are detected in time.
Innovv recommends placing the radar detector at an angle of 10° degrees. I placed the radar detector horizontally. In my opinion, the radar detector detects vehicles sooner than at the recommended angle. I have not been able to physically measure whether this is actually correct.
I have not (yet) been able to test how the ThirdEye works in heavy rain and snow. But with splashing moisture and dirt on the radarunit I have not found any reduction in performance.
Does the ThirdEye have added value? Yes! Certainly, especially in busy traffic conditions, the ThirdEye is a welcome third eye. If you have missed a vehicle, the ThirdEye will alert you that there is another vehicle outside your view.
Is the price of the ThirdEye worth it? I believe so. But that is a choice that everyone has to make for themselves. What is your safety worth to you?
