I wrote a review on the Dr.V's chalk holder and stated that the holder was loose and I hade to use tape on it, well.... that is because I ordered the wrong holder, the new Predator pure chalk is bigger than their other chalk, I spoke to Dr. V on New years eve, great guy, I was able to buy the proper holder from him at a great price shipped to me, he is a pool player as well and designed these because there were no real magnetic holders that you could really trust, the tape has been working fine but I will be happy to have the right holder, this is a great product built by a really nice person who loves billiards, I wanted anyone who read my original review that the problem with the chalk being loose was not the fault of the product but the fault of the idiot that bought the wrong one.
