Seems well made, bends just easily enough to fit snugly. If you are using an aluminum fan with relatively thin mounting surfaces, you might need 8mm screws to avoid digging into the back of the heatsink when tightening the fan down. Dropped this onto a TRX-4 motor and some Touring Car motor, stayed put when falling off logs and running a street track flat-out.
