You list three machines this due is useable with. Is that the only machines? Or are the other machines on the market not been tested? I would like to buy this, but I have had to send products back recently because this was on the card inside the package. And if I opened the package and it didn’t work in my Gemini Jr, then I could t try it for myself because it would be “opened” and non-returnable. Thanks for your help. Other products on the market usually put something like “ should fit most due cutting machines” in their packaging.
