bought this a little over a year ago and I broke it so ordered 2 new nails because I liked it so much, unfortunately the new style cup is much smaller and 4mm terp pearls don't fit you will have to use 3mm not that big of a deal but the inlet whole is larger that 3mm so it's super easy to drop a pearl right down into your rig. The worst part is that q-tips are also to large and you have to jam them down to clean it and they get stuck pulling the whole nail out where you have to grab this super hot nail burning your fingers to pull the q-tip out.
