Saw a contractor on YouTube use a floor leveler compound for this. You pour it thin over the low spots and use a long straight edge to pull it level. The key is to work in small sections so it doesn't dry too fast. Lets you feather it out smooth without a big height change.

Try feather finish patch mixed with thin plywood shims for really bad spots. That combo lets you fill low areas without adding too much height overall, which keeps your trim fitting right. It's a bit of a messy process but saves the original wood.

How is tossing old tablets better than paper waste... just a thought.

Wait, you're agreeing now? Seriously thought those tools were just overpriced gimmicks. They're actually that important?

What did they claim happened? @xena_king22 They always blame a sensor glitch first. My bet is it was bad code that got confused by the shoe's shape or color. Usually it's both cheap sensors and lazy programming. They cut corners everywhere and then act shocked when it fails.
