"I say again - you have no idea of what reliable is"
If I have a torch and I am out at night relying on the torch to find my way home and my battery fails then I would find it unreliable.
Same thing if I am out at night relying on street lighting to find my way and the lights go off, I would have found them "unreliable". Also, if I am in the middle of cooking a meal and the power goes off, I would find it unreliable. (That has happened recently.)
What is your idea of reliability? Mine is "always there when you want or need it".
