Firstly a good point for the delivery and the description is consistent with the Amazon product. By cons to mount, it must be a little handyman. 1. A nut "Nylstop" in the package was not tapped. Therefore impossible to mount. I had to buy more nuts because it is not sold individually in stores. 2. The angle of the display is not correct. I could not see the numbers correctly. (I measure 1m70). I replace existing screws with longer screws and place a block under the display. 3. The saddle is too low. I had to make 2 additional holes to find almost the feel of a real bike. (Which does not prevent to lower the saddle to build muscles différemmenrt) 4. The forces of cable connection is not obvious without a design or a clear photo.
Regarding the use (after adjusting all the previous problems) is what I expected. The force settings for the time suit me. I recommend this product especially at the discount price is exceptional.
