I've picked this up from GC, and there's a whole lot that I like about it. It's light, of course. It's got wheels. It's full rack depth. It's pretty decently made for what it is. But having said that, it's still a soft case over a thin frame, and I'm concerned about the front panel. It's well padded and sunk into the case (the rack rails are inset maybe an inch or so). But still, I'm not sold on whether it provides enough protection.
Here's what I love about it. The large storage pocket (on top when the rack is laid down flat for use) has two slots that open into the rack. So you can leave your MIDI/CAT5, XLR and 1/4" output cables, and the power cable to run out to my powered speaker all plugged in to the Axe and power conditioner inside, and then have them coiled up in the storage pouch ready to go. No plugging/unplugging even for cables that run external. Granted, many other racks would have some space in back to stuff cables in similarly, but this is cleaner. In fact, I wouldn't need to open up the back panel at all except that my power conditioner has an attached cable that's too big to fit through the slot. If I settle on keeping the case, I could probably widen it a bit to get that through, and everything would be up in that top pouch, plugged in and ready to pull out.

As much as I like that, I remain concerned that it won't protect as much as one of the roto racks from SKB or Gator. I won't go heavier than those, and I don't think I really need a rack case. But a roto case seems like it'd offer better protection, especially for the front panel, and with a similar size and weight.
