Rubber door Seals

Hello, I need to replace all of my land rovers Rubber seals around the doors as the old ones have perished. Kits with all the shaped seals are crazy expensive. You can by 1 meter lengths of door seal from LR Parts, are these any good? What are your thoughts? The shape looks a little different to the current seals. Also was planning on getting 8 meters, would this be enough?
Link Bellow, Thanks!

I'd personally stick with the original type, the single piece can fit but not without modification.
