Fits my Palmer Macht 402 poweramp perfectly, with the exact depth I needed with the back of the amp exposed for easy access when the lids are removed. I can see what I'm doing comfortably as a result.
Easy to carry around, even if it does have a little weight to it, which is not a bad thing, as the amp feels protected, but its certainly not heavy. The latches for the lids are of good quality, and feel robust.
Very sturdy, well made, and great quality for the price!
