Feature:
It includes light-duty casters and internal straps. It does not include any accessory storage.

Quality:
The case is made in China. The casters are light duty and would probably not stand up to a drop off the end of mini van or truck. The straps that are supposed to secure your keyboard depress the keys. No moveable padding is included so if your keyboard doesn't fit exactly and the keyboard moves laterally, you're going to see the straps torqueing your keys sideways.

Value:
This is an expensive product to not have fit exactly right. Because there is no adjustable foam interior, you're at risk of damaging your keyboard if the case doesn't fit your keyboard exactly. Ignore the tables and the links that say "Users who bought this also bought..." and do the measuring yourself. The strap retention system will still allow the keyboard to bounce inside by yanking the straps against the keys. A better solution would have been to stabilize the frame of the keyboard with a length-wise pad inside the lid of the case. Unless your keyboard fits exactly, this case turns into a project with you adding the padding ($$$) to prevent damage.

Desirability:
It's going back.

Sound:
It sounds hollow.

Support:
We contacted Gator re: the keyboard flopping around too much in the case. We chose the case size from the table on their website and the case is simply too large for our keyboard. Like an apple in a bucket. The manufacturer's recommendation is to pad out the case with material from Home Depot.

Overall:
Even if your keyboard fits exactly, the strap retention system could be a problem. Don't rely on the manfucturer's tables and measure your keyboard/case measurements yourself to ensure a good fit. In this age of heavy duty skateboard wheels, the light duty construction of the rollers is a disappointment
