This is a good bike box for my Specialized E bike. Being an MIK compatible it clicked into place during the first try. It is secure and looks good on my bike. It comes with two keys and MIK plastic key to remove the box. Instructions for it was damaged due to being tapped on the paper.The only main issue it is a little short for me. I cannot put my helmet inside if I have a few small things with it and close the box. Otherwise it is nice to keep my items dry and put the weight on the bike and not on my back. I wouldn't give the lock much hope in stopping a theft since the lock looks easy to break and the box is flimsy around the key hole so don't keep anything valuable in there.Update: I am dropping a star after a month the lock is failing to close properly and it takes multiple tries to lock the box when it full. I really wish they made it deeper by 5cms.
