The speaker covers on a Nordic track treadmill have rusted less than 1 year after buying it. However you can't replace the covers alone, the whole console would need to be replaced.
Customer services aren't interested in sorting this out under the warranty stating that the rust has been caused by a sauna or shower which invalidates the warranty. They have made no attempt to actually assess what has caused the rust, someone named Michael just decided on his own without any investigation.
He simply wanted to avoid having a warranty claim.
I won't be buying from this company ever again and I'd recommend anyone to stay well away from them. Crooks.
