Thanks just checked $11.87 US but 25% exchange and $9.95 shipping to Canada :-( I took apart another one that I found years ago and the small rubber dots have a checkerboard surface to them while mine are flat. Guess that might be the issue.

 

$2.22 and free shipping from Ali Express, just ordered one. https://www.aliexpress.com/af/key-fo...hr&blanktest=0

 

That was my suggestion, I got these three or four years ago no more problem!
