    This is the coolest and fastest package in my 25 years of life! Ordered 21.02.2020, received 25.02.2020. Brought the courier right to the apartment door! It works. All components are in place. The backlight works. The battery was discharged, white paper. The computer is unreal! Big! I don’t know what it’s gonna be like during the revolutions. I’ll check when the season starts. The review will naturally supplement. And the store I wish prosperity, go to Bali, and ride on the coolest car in the world! Thor! Thor! Thor!

On-what the seller asked to send him the video, gave his e-mail (sent 2 videos, with unpacking and with defect). C (@ not received. The letter came to him either with (@ or C (@ The seller responded for 12 hours and offered to send me a new bike. Which of course I agreed. Short!

  30. O***v

    Ordered delivery from Moscow, delivered in 3 days via IML, to the door. This is my first speedometer. Instruction in English and a little is not clear, the benefit on yutuba there are many reviews of this miracle. Installed quite easily, I bought a wireless. The only hemorrhoids caused the wheel to freeze, as I have 27.5 inches, and in the instruction of this radius there is no such radius. And the Senser does not work very much, not every press reacts, maybe only I have so, maybe because China. In the rest, I’m happy with everyone, I recommend the store how I run the review. Photo attached.
