Awesome accessory. Machining is as flawless as anything else StattQualm makes. Not necessary, as I find the stock smooth topcap to be easy to turn as well, as long as you keep the O-ring lubed and give it some time to break in. But it's great to have if you often find you have slippery hands. Looks good on the A[rise], I was worried it would ruin the looks of the RTA but it does not.

Almost stopped using my A-Rise until this was released. Always struggled to open the smooth cap, but the quality is as good as expected & As always CremeDeVape are always my first call for high end accessories.
