Ax trade 330T thicknesser

I’ve had this thicknesser for 18 months and now the threaded bars have suffered a catastrophic failure and now the machine is unreparable . They say it’s user error but looking at reviews and the fact they have stopped selling them has made me wonder . It’s probably had less than 40 hrs worth of use and it was a trade rated model
Anyone had issues with this one
As it did go back to their workshop a year ago
