Just got back from a business trip and finally tested this little red door jammer properly. Here's my take:

✅ The Good: Super easy to install (literally takes 3 seconds), feels sturdy with that aluminum alloy build, and the rubber grip worked perfectly on my hotel's tile floor. As a solo female traveler, it gave me serious peace of mind.

⚠️ The Okay: The 0.19 inch door gap requirement is REAL - almost didn't work at my sister's apartment where the door barely clears the carpet. Had to really wrench it tight.

❌ The Bad: Tried it at a Vegas hotel with thick carpeting... total fail. Slid right out no matter how hard I turned the screw. Also saw some reviews saying it failed on cement floors - seems like smooth surfaces only!

💡 Pro Tip: Keep the carrying pouch in your luggage - I almost lost mine because it's so compact (about soda can size).

Overall? 4/5 for me because when it works, it WORKS. But test it at home first with your door type!
