I got 3 of these cages, they are pretty light for the material, and are are very sturdy with a very good an smooth surface finish (I only had to use a screw driver to remove small bits of aluminum swarf from one of the cages).
They fit without any shell cutting in stryfes, but might require minimal sanding to fit a rapidstrike, however some sanding might be required based on the type of wheels you use.
If you use ourofdarts' motor spanning board or motor spanning MOFSET with XT60 connector, you'll need to do some shell cutting to fit the female connector (although this will be the case with any cage, not just his one).
And finally these cages are optimal for use in worker swordfish, it needs no cutting nor sanding, just drop one in and close up the blaster.
