After testing Command Medium and Large Picture Hanging Strips for 6 months in my rental apartment, I can confidently say these are a game-changer for temporary wall decor. The 8 medium + 8 large combo pack offers versatility – I used mediums for lightweight frames (like my 8x10 vacation photos) and larges for heavier gallery canvases.

What blew me away: The 3M adhesive technology actually works as advertised. My framed Beatles poster survived a summer heatwave (90°F+) without budging, yet came off cleanly when I moved – just pull the tab slowly downward like peeling a banana. No cracked drywall or landlord drama!

Pro tip I learned: Alcohol-wiping surfaces is CRUCIAL. The one time I skipped this step, a large strip failed after 2 weeks. Also, avoid fuzzy frame backs – I solved this by sanding rough surfaces lightly before application.

Surprise win: These aren't just for pictures! I mounted a small metal shelf in my bathroom (holding 3lbs of toiletries) using 4 large strips. Still holding strong after 4 months of steam exposure.

Watch out for: Paint compatibility issues. In my bedroom with cheap builder-grade paint, removal took off a nickel-sized chip. Test in an inconspicuous spot first. Also, the 'clicking' sound during application is oddly satisfying but easy to overdo – press firmly for 30 seconds, not until your fingers cramp.

Value verdict: At ~$0.87 per strip pair, they're cheaper than buying individual picture hangers. I saved $15 vs. buying separate medium/large packs at Walmart. Just remember: heavy items need multiple strips – my 5lb vintage mirror uses 3 large pairs in a triangle pattern.
