The advantage is that the color is gun meta. The key seems to be high security prevention Is not it a lighter one? You can take part of U The disadvantage is that you do not have the feeling that it can be taken out by force if the connecting part of U gets serious Kakakacha. It is unknown how much this actually enhances the security. I thought that it was suitable for the price.
The weight of the product is 237 g (237.0 g) of the U-shaped rock and 6 g (6.3 g) of the key by actual measurement. The U-shaped part is a form that leaves entirely when the key is removed. There is some rattling while locking but there is no hindrance to use. The size could turn around and fix between the wheel of our road bike and the seat tube, it was just right. I think that it was better to have scratches on the bicycle frame if rubber or resin protective agent is in the U shape, but I am satisfied because the price is price. I am planning to use it by devising such as passing rubber tubes on my own.
