I just received my Filofax Finsbury, in Electric Blue! I also selected A5 for this planner. I write rather large, and this one won't travel with me, so the bigger size was preferred.
Being that my first Filofax was the gorgeous, patent purple, A5 Original, this one wasn't quite as exciting to receive. The Finsbury's construction does not seem to be of the same quality. The rings are larger and tight, which I LOVE, but the leather feels lower in quality, and the back inside cover feels slightly tacky. It's hard to explain, but it feels different from the leather on the rest of the planner. I covered that section with a piece of plastic straight away, as I felt like it kept the pages from moving to a good position when the planner was closed. (Although, I still have to move the back pages to an uncurled position each time I close it). Then again, that might be happening because of the larger rings.
The other issue I have with this is the color. This this is NOT blue in any way! Unless you count the thread in the stitching! The leather is definitely purple and black. I don't mind that one bit. I do love purple. My only gripe is I ordered blue papers to make dividers with. No big deal though, I'll still use the blue paper. If I'd read more reviews, I would have known before cutting the purchase.
I may grow to love this one as much as my Original. I will update again when I've customized!
