Just to be clear, the Gator ATA case I use is for the 61 keys keyboards, not the 76, so, is much more compact in size without compromising the Tyros 4 in anyway.

Very little lifting, since it has wheels, and quick to open or close, just 2 "keys" hardware that have never give problem, the YCTYROS2 did have more "keys" and three fall apart with the usage, so, I can say that they are not built to last, at least vs the Gator ATA case.
