Yes, the TF3567 is supposed to fail if something goes wrong. I was a 73 year old accountant last year when I got my LCT, and I have no mechanical ability at all, and am fumble fingered. I am still using the original one. All you have to do is read the instructions, and not ever try to turn the turret unless the TF3567 is on the square portion of the index rod.
To me the LCT in auto indexing mode, with the Pro powder measure and the safety prime is a marvel of efficiency at a very small price. The only thing you have to do with your left hand is set a piece of brass in the shell holder, set a bullet on the case, and remove the finished round. Your left arm might wither away if it wern't doing SOMETHING!
