I received mine today and it works great. One potential problem for others is that I had to dremel the Pro Wrestling cart casing where the everdrive passes through the cart pins on the bottom. The solder joints directly above the pins lined up directly with the plastic of the case and caused the case to bulge there without modification.
I am not certain if this would cause other users to damage their everdrive or SMS if left unmodified. I noticed it because the cart slid rather tight into the Master System cart port and fixed it.
Otherwise this is absolutely wonderful to have, thank you KRIKzz.
