Is the Grevia cheaper now? Does that mean the materials used are inferior?

Don't worry, they will definitely cut corners where it's not visible. Toyota won't do a losing business.

I bought it in October, and there is no abnormal noise.

The materials are already pretty bad, with a full-on plastic feel, so how could it get any worse? [I need some peace]

It feels very plastic, lacking in tech content.

This thing is more expensive than what is sold in the US, or at least the prices are similar, even though labor is cheaper in China and the cost of parts is also lower.
