The idea of an "adjustable" sock blocker is brilliant - sadly, it is a nightmare to use.
The adjustment expands in increments, allowing for a *somewhat* large range of sizes, but it never seems to *stay* expanded during use.
Even if the blockers stayed at the adjustment they were set at, the socks get snagged by &/or hung up on the corners of both pieces. They start to slide onto the rounded toe easily, but they get caught on the square points of the "body" just above the expansion opening.
I know some people complain about the opening between the two parts making a "divot" I the sock when they are dry, and also grumble about the instability of the expansion joint.
All-in-all, it's a total failure when it comes to usability.
The question that percolates in my mind is this: "Why do they need to expand? The very nature of socks is that THEY expand. A set with 2-3 basic sizes is all anyone really needs. Everything else is just hype & dust bunnies."
Honestly, I think the overall design is lovely IN CONCEPT for people who knit socks in a multitude of sizes; but SERIOUSLY - *who does that.?!*
Were I to design my own sock blockers, they would be made from the same pink lucite that the Tula Nova cutting templates are made from, shaped like a standard sock blocker, but hollow all through the center to allow for fast blocking.
A girl's gotta have a dream, right?!
