Hi, glad and happy to find this forum. I´m not suscribed nor registered. However I´d like to share my experience dealing with this belt. I own a MDS-JE440 which had a "Bracelet" as @sjopun is mounting. It worked for couple of months. So I looked for the replacement part, but surprise! I is located in UK or Greece. I live in Chile (South America) and shipping from there to here is really expensive, rubber cost is about 6 dollars and shipping cost is about 60! Then I looked at Aliexpress (china) and found a square 0.7 mm section, 27 mm foldered length (basically is the half of the diameter). It cost less than a dollar and shipping cost to Chile 1.5 dollar.
Hope this help
Cheers
