They really are convenient. They won't match with every attachment, I still use a carabiner for some movements, and it cuts a few inches when doing lat pulldown.
Not the same exact one, it's a copy. It does the job, but honestly it's a pain to use. I'd rather get the machine version from Titan for the convenience.
Not the abmat one, but something similar I could find here in Canada. Good product, really like the flat surface for putting my knees while doing mobility work.
