I'll admit that you really have to lathe the PVC into the cap but once it was fixed I had no problems with it falling out of the cap. They're not business quality so you might need to hold them or find a way to secure them so they don't slip, but I put resin on my cups at night and they still run quietly in the morning. I use two that I bought for about 2-3 months and I like them for the price. These turners compare favorably to their metal or branded counterparts. If you're willing to be patient and try to fix the problem, you'll be rewarded with a decent quality product. I was also able to increase the PVC size to 1/2 so I can create detachable tips and the PVC fit perfectly in the pre-drilled hole. I am happy with my purchase.
