Review on π² Sanding Mouse Block: Optimal Backing Sandpaper for Effortless Finishing by Justin Ewing
Not flat! in sanding blocks
I have other perfectly flat sanding discs and they work 5 times better than these pads. They are very convex, with only a 2" circle touching in the center, making sanding slow and tedious. They are useless for finishing primers or polymers.
Pros
- delivery was very fast
Cons
- unreliable
