I asked the seller so we shall see what the diameter of the driver is in this thing.
Edit: Found a cheaper variant of the same product from a different seller
Look what I found on AliExpress

...€37 what a steal, still need to here back on the driver size, I may pick it up if it’s an ideal fit and grab myself some custom drivers
I'm so tempted to grab a pair of these, whats there to lose
