Here's the lowdown for anyone who doesn't know.

They are copies, not official Floyd Rose products they are based and copied and paid off floyd rose designs but are Ibanez, which is a reason they are not so good. I've owned all Ibanez copies, Licensed Floyd Roses (which is a Floyd Rose product), Official Floyd Roses (the best), Schaller Tremolos (like Ibanez their based of Floyd Rose designs and they kick ass too.
Floyd Rose makes generally five main bridge products, each having variations.
Licensed Foyd Rose tremolos
Official Floyd Rose tremolos
Seven Foyd Rose tremolos (which is a 7 string variant of the OFR)
Speedloader Foyd Rose tremolo
Speedloader Foyd Rose fixed bridge
what Ibanez makes, their tremolo systems for their 6, 7, and new 8 string are not owned by Floyd Rose but are paid for because the patent was already made by Foyd Rose. That's why it says patented under Foyd Rose.

<---playing fast
the Ibanez tremolo bridge in my seven string was horrible! once when i was tighening the blocks that lock the string in place is actually snapped the string and it was my only one, since that bridge allowed you to use the ball of the string instead of snipping it off (which is better actually)
