Decided I was. For Sigma cycle computer, because of the good reviews on the Internet On various websites and forums in the technical details were approached addition, there was a couple of work colleagues the information that they also have a unit of Sigma in action. At first I was hesitant because of the various models of Sigma, but after visiting the publisher's website with the comparison function I was then sure what I wanted to have me. Actually, I would have given the article also 5 star, it is technically really what I was looking for and expected. One point deduction comes through the contactor which you have to attach the pedal, that's really not a good solution (but falls to me no better one). Positive that is you really get everything delivered to directly receive his routes and the device is really easy to handle. Installation was quick and easy, commissioning, as well. Also, I can use the computer with the included strap for my running sessions, that's really great. Whether I'm going by bike or running go, I always order the chest strap and can track my heart rate. Using the computer is also more accurate to calculate the burnt KCal able. When wheel more precisely, because the computer, etc. have the data such as temperature, altitude, cadence, speed to calculate everything. The model is really great for all my applications, I really think about but to award 5 stars ... The newer models of Sigma still have a Ghost function, because you can go racing against yourself. But that's not interesting for me, I have decided the right place with the model. So, again briefly to the point why it gave a star deduction (a half star deduction would have been better, but unfortunately is not possible). You have the contactor for cadence attach to the pedals and that's not in my Cube MTB so easily possible. The arm of my pedals where you have to fix (towards the frame) the contactor on the inside, there is a recess. One can the contactor with the tape while "attach", but do not attach correctly with the enclosed cable ties. After the contactor has now been solved quite a few times and has slipped on the pedal arm and has thus reported no proper cadence more to the computer, I have broad transparent tape wrapped around 2-3x. Now is not nice ..., but functional. Anyway, I am very satisfied with the overall package and I can recommend the Sigma BC 2209 MHR good knowledge.
