My initial concern was that the adhesive might be prone to wearing off after a few reapplications. Their FAQ addressed that point, though not in the way I'd hoped: "Like normal stickers, they are designed to be stuck exactly once. Since the adhesive takes some time to reach full strength, if you are careful, you can peel the stickers off right away, but this causes the sticker to lose some of its tack (which can make faulty connections in the circuit)." Certainly, reapplicability would be a design challenge in itself - I can't fault them for eliminating that concern. Still, it would've been fun to see. Maybe a future version?
