Although the converter feels a bit heavy and ungainly, it's super easy to use. You just slide it right under the cutting area of the sizzix machine and the powerful magnet pulls it right into place. It doesn't shift out of place while you are cutting. It hangs in there easily and with no fuss. Popping it off is just as easy.
This converter makes it so I rarely use my sidekick anymore. I just pop the converter on and cut all of my sidekick dies in my original sizzix machine. I love it!
The only down side that I see is that sometimes I have to pump the Sizzix handle a bit more for the sizzlit dies than for the original dies (done without the converter, of course), but this doesn't really bother me. I still like the pump action handle better than trying to use the Sidekick and it works fine with 3 or so pumps of the handle. Definitely worth it.
This wonderful adapter allows me to use my old sizzix with not only thew sizzlits but also with cuttlebug embossing folders! .........I'm thrilled!!!!!
I found that this item turns my original red sizzix into a great machine to smash bottlecaps flat for use in crafts. Works perfectly.
