Einhell is really hit or miss.
For DIY Lidl has a fantastic lineup, hand and power tools. Their battery ecosistem is really good, and batteries are half the price of Brand names.
Their black tools (Performance) are prosumer level. They can't go head to head with DeWalt, Makita, Bosch blue, Milwaukee, etc. But they are definitely above The Ryobis, Bosch green, Black and Decker, etc. I own quite a few, and some are truly impressive.
I owned a sign shop for over a decade, so I kind of have an informed opinion. We were 80% Team Yellow, and I still keep a few. Also, the newer generations are just not the same as 10-20 years ago. Most of the DeWalts I kept were made in USA, UK, or Germany. Not usually the case now.
I haven't owned Makita, but have only heard good things.
We had a couple of Hilti. Hilti is on another level, but you'll pay for that quality.
