I bought this third roller because the new one was making such a loud noise. It was the bearing at the end of the strap. There's no obvious way to lube the bearing or take it apart, and I don't even know what it's made of. The first replacement product fixed the issue for a month and two days (essential as you can return an item within a month) but this second product is a little better. Now the bearing at the end of the belt has noticeable play and the loud hum is back. I also noticed that the metal rod got very hot so I guess I'll have to replace it again to avoid a fire! PS The proposed support site is for a corporate site that has nothing to do with retail customers - be careful!
