This was the only portable rack case I could find which was deep enough to house my Ashdown ABM600 Bass Power Amplifier. All others were just too short. The zipped mesh in the lid is very useful for storing power/speaker cables, though it would have been nice to see this on both lids. One other small complaint is that the inner plastic has no mounting points, nor do the racks have inner rails for affixing the rear of an amplifier (such as mine, or the Ampeg SVT-4-Pro. Without these, the amplifier is only supported by it's own ears; which of course is fine if the ears are steel. Not so much if they are thin aluminium.
Other than that, the handles are sturdy, the plastic is tough and it takes a lot of abuse. Overall, very good.
