Review on 🔧 StarTech.com ExpressCard Stabilizer Adapter - Pack of 3 - 34mm to 54mm ExpressCard Bracket - ExpressCard Stabilizer 34 to 54 (ECBRACKET2) by Joshua Wheeler

I ordered a pair of 34mm ExpressCards that fit in the 54mm ExpressCard slot. The adapter just snaps into place and really saves. I had to modify an adapter by expanding the slot at the top with a key for one of the express cards. On the other hand, it worked without modifications. I found it by accident. It must be listed as a recommended item for any 34mm Express card.
