Two people on facebook groups have said they have stopped working. Haven't posted the cause.
Yes iv'e had two reports, and both my fault, one i forgot to fit a spring to it during assembly, the other forgot the rubber seal.
Rushing during assembly
Both Replaced
Please trust you will get a replacement if you have any issues.
If i have 2 or 3 reports of a certain problem then i will strengthen that component, but time will see.
In the mean time enjoy the product, and don't worry.
Steven.
