Okay, so I finally got my hands on this sanding block kit after seeing it all over DIY forums. Here's the real tea:

The Good: These foam blocks are seriously versatile. I used them to refinish an old dresser with weird carvings, and the different shapes actually reached spots my regular sandpaper couldn't. The flexibility is perfect - stiff enough to sand flat surfaces but bends just right for curves.

The Bad: Whoever included those stiff sandpaper belts clearly never tried wrapping them around foam blocks. Total mismatch. Just use your own PSA-backed paper or regular sheets (though you'll need gloves - learned that the hard way when my fingertips turned into sandpaper themselves).

Unexpected Win: The storage case is low-key amazing. No more hunting through my toolbox for that one sanding block that's always missing. And they're so lightweight I can literally carry the whole set in one hand while working.

Final Verdict: For $20-ish? Solid buy. They won't replace all your sanding tools, but for tricky contours and detail work, these foam blocks are game-changers. Just... maybe gift the included sandpaper to someone you don't like very much.
