I think based on the trends it appears to be somewhat random, but mainly usage patterns with the heaviest users logging on the most mileage eventually having issues, which doesn't explain the inconsistent performance problems and DOA's.
If any of you members were around long enough do you remember the Cloud+? VXL blamed it on a rogue manufacturer trying to steal their design and intentionally sabotage the product? So Cloud+ customers were having their Clouds+'s go belly up because heat would cause a wire to fall off the heater rendering it useless. Well, what happened? The company nearly folded and instead started a kickstarter which became the VXL EVO.
I wonder if something is happening like the GH is being made in China, and some parts are either inferior in design or there is something in the electronics that is causing so many issues, however it appears that the temp sensor (straight to blue) is the result of resin and not being able to maintain properly? The back ends on the other hand could just be bad manufacturing, or who knows what, but it is a product that CAN work, and go the distance that's forsure as i've experienced it for a protracted period myself.
I'm starting to think that the LIFETIME WARRANTY isn't due to confidence in the product, but more of a matter of they had little choice, when the device is so in its infancy. As reliability improves, and they have stronger faith in it, i'm thinking that the lifetime warranty could in fact turn into a standard 1 or 2 year.
I personally think that the GH is still in its beta stages, and there will be a turning point that will increase durability and go the distance, I just hope it's soon.
These are just my thoughts and opinions and based on my own inner dialogue so take it all as you will.
