The helmet is light, the magnetic lock well - if you're used to it - and the helmet does not look the the usual alien chest. Fits fine to a retro bike. The LED is "nice to have" - well if you did. I would not leave it, because the battery is often frightening for all small a LED. If one notices not only at home or because the lamp's back. Hence a Ersatbatterie little help - and it is fiddly to change. Even without LED function: SUPER HELMET.
