I had a Flex 14 which had a broken keyboard. Sent it for repairs and it came back with the same issue happening a minute after I turned it on. Had a bunch of friends who got a Lenovo gaming laptop that were offered at a deal with our school (was a Y-something I can’t recall). All of them ended up with strange green bands on their screens within 2 years. The whole superfish fiasco basically cemented that they’re not a company I would buy anything from ever again.
I’m currently using a Asus Zephyrus G14 and it’s been practically a flawless experience.
