Rode NT1 5th Gen Repair Experience Muffled Internal Noise Issue

I get my Rode NT1 5th Generation back today from the UK repair service, they have had it just over a week and fingers crossed it works. There was a muffled noise coming from inside when handled and tapped which a same mic didnt do. They said the housing was slightly deformed and replaced a capacitor as a precaution. Really hoping it works or I will return them to Amazon which I dont want to do as they do sound amazing otherwise. Has anyone else ever had noise issues with microphones like muffled sounds or rattling inside thats hard to find? I had this a LONG time ago with some cheap condensers too just wouldnt expect the same from Rode of all brands at the pricepoint too.
