Thats terrible.
The legal situation here is very clear.
If a defect is present at the time of manufacture, which this problem is very clearly, the retailer is obliged to recompence for up to 6 years from the time of purchase (5 years in Scotland).
So tell your mates to go back to the shops, explain that it a known manufacturing defect, and demand recompence, do not be fobbed off.
I am not sure on the exact detail or whether its exactly correct ..... but I seem to recall that if a retailer attempts to avoid their legal responsibility by for instance attempting to claim they are not liable to replace goods that are faulty, they commit an offense.
> Both have sworn to never go back to Silva and have told clients, friends, customers and anyone who will listen to not go near them.
Cant disagree with that and, reluctantly, I would advise the same.
Duff stock, with an known manufacturing defect that retailers (or Silva) have been aware of for possibly 3 years or more, is still in the shops (well it was a few weeks back).
