I have used not thinkpads but Lenovo IdeaPad from 2023. Very fragile. It has caused me to run many times to the repair shops.

Whereas Lenovo laptops (non Thinkpads) from 2007 and 2021 are very solid nearly unbreakable.

Only the expensive business models of Lenovo are known for their quality. Their cheap models are as bad as any other company's.
