Waited a few months to post to get a true picture of this case. I have NOCO GB 40 in a suitcase and always carry it with me. My mower's batteries need to be charged when it gets cold, so I have a cover on the mower where it gets dirty and dusty, but the airflow cleans it up quickly. As advertised, fits perfectly and seems to hold up to my abuse. If it were bad I wouldn't hesitate to buy another one.
