I like it so much I will be buying my daughter one to put on her desk at home. Im hoping they are as durable as other reviewers have stated. Well guess what? It started pulsing but stops every time. I?ll probably end up buying another pair for next year. Like day and night difference. Works great, perfect replacement/spare if you step in something sticky. If it was made from string they would be perfect but its in the description. Für das Training zu Hause finde ich sie ideal. Came with its own pump and is easy to inflate. All day, all night, all the way until he rides it again.
