Tracey cox superset rechargeable toys

I have both the Tracey cox supersex bullet rechargeable vibrator and the supersex g spot rechargeable vibrator. They started off as the best toys I have ever owned but after a while they each developed a fault where the light would stop flashing to show they were fully charged but when I pressed the button nothing happened.
I reported one of them as faulty and got sent a replacement but now have the same problem with the other. Is this a known fault?

Not really.
I have a most of that range as my wife loves them, none of them have developed any fault yet, some of them I’ve had for around 3y now.
