This is an excellent case for the price. It's made from tough, durable black polyethylene and is ideal for local gigs; it's not as tough as a flight case, though.
It comes with four latches and one is a TSA locking latch. It has an internal dense foam wedge block with a small apron attached. You place the block at the end of your keyboard and then sit your keyboard on the apron. That stops your keyboard moving around and keeps the foam block in place. It also comes with two large squares of dense egg box foam, which you can position to suit your keyboard.
I took a chance and bought this case for an Akai Professional MAX49 keyboard and it fitted perfectly; a very snug fit width-wise. Length-wise, I had plenty of space for the USB lead and the power supply and you can through a few other items in there, as well.
Gator always seem to make decent cases and this is no exception. I also have a Gator GR-6S, 6U, 19" shallow rack case for my Kemper Profiler and some other 1U rack units, and that has also been a very good case.
Overall, it's an excellent case, as I say, it's not meant to be a flight case, but there again, they cost a lot more and are heavy.
I'm very pleased with it, comes highly recommended.
