There are high-end brands that spec products to a high standard and have them made (to that standard) in China. But I agree, GP is confusing high-price with high-end.
That said, thermometry is pretty easy and well understood and you don't need crazy accuracy for cooking, so 'low-end' is fine really, just don't pay high-price for it.
Yes, not sure if you meant that to be disagreeing, but I completely agree. China has is at par with if not surpassing the most advanced manufacturing capability of anywhere else in many areas. It can just also offer very cheap poor tolerance mass produced crap.
