Just got these sliding door security bars and WOW - they're way more versatile than I expected!

First off, the adjustable length (16-51 inches) is perfect. I used one for my patio door and the other for a janky rental window. No drilling, just plop them in the track and boom - instant security upgrade.

The metal feels super sturdy - like 'could probably stop a small car' sturdy. My favorite feature? The removable extension rod. Didn't need it for my doors but threw it in my luggage for hotel stays. Hello vacation peace of mind!

Pro tip: The little latch can be stiff at first, but after some wiggling it works smoothly. Also love that it doubles as child/pet protection (my cat keeps trying to ninja her way onto the balcony).

Only con? They're lighter than expected, but after testing with full body weight (don't tell my landlord), they held up perfectly. Already ordered another set for my mom's place!
