I have invested a lot of time to figure out the right size. This case has the right size and well thought out. I no longer need to drag the tools to work. In an age of than 60 years one looks around for Erleiterung. The design as Trolly, the low weight and the additional pockets (inside and outside) with partial equipped Kettverschluß I find I very well. The shipping was fast and the item was well packaged.
