I have invisalign on the top and metal on the bottom.
My top teeth have always been essentially straight, but when I decided to finally straighten my very crooked bottom teeth, I figured I'd get the top perfected at the same time.
So, other that some pretty minor refining, the only significant movement I needed was my lateral incisor and my canine rotated together.
I never in a million years expected my super-crowded bottom teeth to be finished before my nearly perfect uppers!!!
However, here I am on my last aligner, unlucky number 13, and I need refinements because rotating canines is apparently like trying to move mountains!!!
Now for the pics! Forgive the massive staining around the invisalign attachments, I tend to drink coffee while on the computer
At the beginning, my top teeth aren't bad, not *perfect* but still good

bottoms, not so pretty

I didn't take any pics of the upper sides until halfway through, see the canine incisor issue?

Now today, better, but not much consider how many aligners that was

other side is picture perfect though...but it didn't need much adjustment in the first place

Front

So, I have another 2 months or so left on my lowers, and with the wait for refinements, I will be in invisalign quite a bit longer than that.
Some people would be happy to get the brackets of first, but I really like my metal mouth.
Oh well, I'm still thrilled that I'm finally going to have beautiful teeth, so I can't really complain!
Besides, 13 aligners is nothing compared to the rest of you one here, so a little longer is just fair, right? LOL
