The answer is pretty simple - it's a forum and we are here to discuss thing. If someone doesn't want to read our discussion about certain things, he should not post about it or even use a forum. Simple.
Perhaps I didn't use the right words. I don't have any problem with anyone here—especially not with debating things in this forum. That's exactly the purpose of being here, right?
Ten years ago, there was very little information about Chinese carbon frames. If it weren't for the early buyers who purchased them, tested them, figured out which ones were good and which were bad, and shared their experiences, we'd all still be in the dark, wouldn't we?
Today, the Chinese frame market is well established. Thanks in large part to this forum, we all have a pretty good idea of which manufacturers are reliable and which ones to avoid.
Now, drawing a parallel to Chinese power estimators: by now, it's widely accepted that most of them are inaccurate and unreliable (with exceptions like Magene and maybe Geoid). Point. That's it.
There are one or two isolated voices here claiming their unit is good and reliable, but they usually rely on non-rigorous tests, so I wouldn't put much stock in them.
But there's a key difference: a crappy frame could potentially fail catastrophically—leaving you with fewer teeth in your mouth, or worse.
My crappy power estimator, as far as I know, won't break, explode, or cause my bike to fail. The bike still works fine (it's not ok to compare it to a square wheel bike). I can ride normally, I simply ignore the inaccurate numbers if I want.
The weight and price of my power estimator is comparable to a regular spider adapter (piece of metal/carbon to mount my crank arm to my chainring). So I ordered the crappy power estimator, I'm using it, I'm fully aware I can't trust the readings, and I'm okay with that. That's the math I made.
I'm not sure there's a real need for more people to keep buying these, testing them, and coming here just to say the obvious 'it's crap.' But with the recent price drops, more and more people will probably get them anyway. Let's just hope they don't end up overtraining—or worse—because the power numbers were way off.
