This was my experience with DeWalt too back in the late 80's when they first came out. Sadly, they too have fallen.
Case in point: I still have a DeWalt drill from 2009's that is still on its original set of batteries. But a hammerdrill I bought for a renovation in 2015 died after moderate use just outside of the warranty and after taking it apart I realized this wasn't an accident but just crappy manufacturing. The mechanism was so delicate it should have never been greenlit and the materials used were sub-standard.
