We use this to store our merchandise (shirts and cd's, etc) so it gets handled quite a bit.
The double springloaded handles are near perfect, the hinges are roadworthy and keep the lid in place when open.
When the lid doesn't close perfectly, it means something is in between.
The latches are also springloaded and work very well, only within a certain amount of time they do tend to stain but they can be cleaned with some sort of metal cleaner.
The wood used is strong enough for what we transport, we also have a larger one where we store some drum hardware.
Sadly there aren't any variants with wheels (without going custom).
The ball corners are not stackable which is the only minor point.
If you need a case that can be transported with ease, get these!
