simple and good. Easy to attach, goes past the Bosch Nyon and you get enough stowed slight things. Heavy like a massive chain lock can not therefore be transported because the weight (2kg with me) the bag pulls down. Who does not particularly stands on chicki Micki is here with little money on the correct side.
Conclusion: Not super nice but secured useful and fast, I would not recommend for occasional use for long journeys or continuous operation.
