I got the 48mm vortex coin. It works great on pretty much all of my nails. I really like being able to use it on the larger size bangers and dishes. I'm hoping to pick one up with a handle eventually. The coin itself gets warm quickly but its still very usable without a handle, get a coaster so you can put it down quickly!
Love it! Works better then I imagined and can see through it! Perfect addition to my t-bucket sett up! They tossed in a few extras also. Love this company!
I'm still waiting for my new 30mm banger to arrive, but I've been using this 48mm cap on my 20mm banger with a 4.5mm sic pearl and it spins great! Excited to use it on the 30mm banger when it gets here!
