D-Lock Mount

I had only used this four times. The yellow catch just fell apart releasing the D lock onto the chain while I was riding in traffic almost causing an accident. On examination, the yellow catch is very poorly designed and does not stand up to useage.

there appears to be a design issue with this product. Applying no more than 1.5Nm torque to the clamp screws a) did not tighten sufficiently to prevent clamp rotation b) stripped the plastic worm band. The grub screws are steel and this is not what the product info states (it states polycarb).Slippage of the clamps is a safety issue if the clamp rotated into the pedals while cycling. In process of claiming a refund. Cannot recommend.

Awful instructions, incomprehensible. Badly designed. Doesn't work
