This was at the easier end of 3* for me, maybe because I had quickly had the ideas that got me started. But enough challenge in getting it right that I wouldn't go all the way to 2*.
Some lovely logic. Thanks!

One of the hardest 3* I've ever solved. The break-in is at least 4* then it gets smoother.

Cool puzzle. Like untying a giant knot where you have to pry and prod to figure out where weaknesses are and then you get a bit of progress and it starts to unravel smoothly and beautifully. Really satisfying.
