This is a Bryton Rider S810. I purchased it about a month ago. I've used it about four days a week. The glass screen has a protective sticker on it, so there are no scratches. However, there are some minor scuffs on the bottom of the back of the unit from light contact with the stem during installation. This model has excellent battery life, but I'm selling it because I bought a different cycling computer. I've charged it about four times. All accessories are included. Please refrain from purchasing if you are concerned about the condition in detail. Bryton cycling computer
