My area was among the first of the US Lidl openings. It was a zoo for several months. 1.5 years later it has slowed down.
It has been interesting to see the changes since they opened. They have eliminated the self service electronic scales/pricing machines that were in produce & bulk food. Not sure if there is still one in the bakery since I’m not a big fan of their baked goods. They have increased the amount of non-food offerings by a lot. My location looks to be adding self checkout stations.
There are some good buys to be had. Prices are usually identical to Aldi’s. My Aldi’s is older so Lidl has a bigger inventory. But my Aldi’s is cleaner, faster and better managed than my Lidl.
