Great wheels like those in roller blades. Rolls like roller blades.
The tolerances in the screw holes are significant and I had to loosen some previously installed rack units to install additional rackmountable units. The reason is that that screws hold not only your rack gear but the entire metal frame with threaded holes as well. If you undo all screws, the frame will come off (not actually a big problem). In theory you can replace this frame if one day the threads become worn out. The butterfly latches work pretty well. It has rack rails at the back, this is a must-have feature for all rack cases.
You have to lift the case a bit to remove or attach back the lids. It's a bit weird and embarrassing but after like 100 attempts I managed it (not really, still struggling when all of your rack slots are occupied and the rack is difficult to lift).
The biggest problem is that the side handles are very close to the recessed sides and when I have to carry this rack, my fingers get pinched all the time, so please take extra care when you have to carry this by the side handles. The pull-out handle is not for lifting!
I just ordered another rack case, this time it will be SKB, I hope it will be better. Overall, this Gator has good value for money.
One last thing, it's not weatherproof, so there are small holes between the body and the lids. There are no gaskets to protect your gear from water, snow etc.
