Review on Numark GTRS - Enhanced Stylus Replacement for Numark's Grovetool Cartridge by Quintin Gore

I originally bought these for my Numark TTUSB player after my stylus wore out after 3 years. At first I was of course excited to be able to play my turntable again, but after about the fourth play a real needle popped out of the rubber. It happened after I *gently* touched it to get rid of the thread of dust on it. So I used the second one from the pack. About 5 games and it happened again. I tried putting the needle back in, but it didn't work. I hope it was just a manufacturing defect as I trade them. Let's see how the next ones will be.
