Review on 🛠️ XUNHON 45° Drop Proof Tools MSL01 - Innovative Bubbles for Diverse Applications by Noe Epps

Just received and noticed that the readings of the four levels are inconsistent when stacked which is odd. I understand that these are Stabila's "budget" line of levels, "repainting" their levels for Type 70A-2 homeowners, but they're still $80 a set. They can hardly be used to mark walls for setting wall ties as they don't have sharp/straight edges but are rounded. I don't see why these lightweight spirit levels are any better than other brands. In fact, the 4 foot level is significantly heavier than the old 4 foot I Beam Johnson level I have.
