I'm probably the only guy who's ever had a problem with them, but I did. I wanted to order a pickup mount for the TEC II crack trigger sensor, but what I got was a mount for a knock sensor which is $5 brass flare adapter that I paid $20 for. Oh ya I needed it quick, so I asked for overnight shipped which was $30. I figured it wasn't worth the hassle of shipping it back and the actual mount is $160 so I said forget it. I know this guys make great products, but oh well. Oh here's a pic of what I paid $20 for.
