Nice little multifunction meter. I bought it for an encrypted record of my little walks VTC with my 10 years I am often asked "How fast roll-you one?" or "How many kms a-te is made from the house?" or "How high are we?" etc. So I'm in a rather playful use because I practice the bike as a walker. I have more functions than necessary. However, I think that people who practice the bike in a sporty way can use the many information issued by the meter for the purpose of evaluation and improvement of their performance.
In any case, installation was very easy, just a few grams more on the bike and found boxes and replacement magnets on Amazon in case of problems. Recommended Buy.
