Review on Acerbis X-Elite Handguards - Black/White (2856891007) by Antonio Baker

Once you put them on the bike they work fully and look great, they don't vibrate/wiggle much either. The problem is that the screws they come with are made of what you could call cheese, they come loose instantly with the slightest torque even with the right screwdriver, and the mounting holes don't seem to be threaded at all. So you basically wind them up when you screw them in, horrible design. As a result of this simple oversight I hit myself with a screwdriver, this doesn't reduce the cost of production of the product including better bolts/screws as most of the cost of production is on the handguards themselves, a patch later and I'm mostly happy.
