Protects the bottom of my glass billy from getting scratched when I put it down.
Broke the end off first time I tried to use it. It also is too rigid to fit past the ice pinch of my 45 cm Billy.
Great idea.
It does fit past the ice pinch of my 45 cm tall 9 mm thick Billy, but barely. It does a great job, but it's fiddly to get it past the ice pinch, both in and out.
These are really helpful. I had to bend them to get into some tricky spots, and that worked well.
