Eh.
It's not perfect, but the price was reasonable. Aside from the tweaks I've shown here I've had to fix the arm of the mechanism. It's a metal arm that was pressed into a plastic piece that drives the press. When bottling the arm just popped out of the piece, ended up hammering it back into place as firmly as I could. Since then it's held up fine so far, but it's still a concern.
I guess my overall view is that it works, and is pretty versatile. Only real gripe is the cost, $80 is a lot of money for a plastic product that requires some fiddling to work properly.
