High quality horn for the cost. I have used much more expensive ones that didn't have this level of clarity, plus the certification is clearly marked so you know it's legit.

I’ve tried everything from hairspray to rubbing alcohol on set-in ink stains, but this is the first thing that actually made a dent. I followed the instructions exactly—applied it dry and let it sit for a few hours before washing. It took two rounds, but the ink is 95% gone. It’s a thick, soap-like consistency which makes it easy to control. Highly recommend for fountain pen users especially.

It's okay i guess. The headlights switch is a little stiff and i'm worried it might break if i force it too hard in the winter. Its cheap though so i bought a spare just in case lol.

Its okay I guess. The finish is a bit more glossy than I wanted and it smells pretty strong so definitely use it in a ventilated area. It covers rust well enough but the cleanup is a nightmare since its oil based.
