These sandals are so beautiful and unique. She wanted to have two different styles. Thank you Leotruny. All I really cared about was the screen and the awesome 120hz refresh rate! I assumed when ordering that it would come assembled. Additionally, you avoid the hassle of taking the clamp off one bike and mounting it to another. The wireless USB stick fits inside the case for transportation or when not in use, so you can?t easily lose it. Unfortunately that is not what I received. That being said, it takes a little practice lifting the bike up onto the rack. The instructions might be a good help with this whole process, only they are exclusively in Mandarin.
