Warranties/support can also put a company out of business. If anyone remembers Quantex/Cybermax computers in the early 2000's. They had good products at a great price, won lots of awards. Their supplier went out of business and then so did they. Leaving many people without support and with broken equipment
sounds to good to be true
I had a lifetime warranty once on a stereo I bought a long time ago. The stereo still works, but the company that sold it is long gone.
My point is, lifetime could mean lifetime of the company, not the device.
