Review on DreamStitch 859815002 Straight Invisible Presser by Jennifer Roberts

I purchased this item after carefully reading the description to see if it would fit my Janome S5. I only ordered it after reading the description that this item would fit my car. Having received the goods today, upon inspection I was afraid that this was the wrong size; this was established as a fact as soon as I attempted to attach it to my machine; Janome S5 requires a 9mm rod and this item is too short; I assume it will fit machines with 7mm bits. Item not listed in the description. Otherwise everything is fine with the product but I haven't used it so I can't say for sure.
