First off, let me say this door jammer is a BEAST. I've tested countless security bars, and the SecuraDoor Masterlock stands head and shoulders above the rest. The moment you hold its 3lb aluminum alloy frame, you know this isn't some flimsy piece of hardware.

The installation is ridiculously simple - just adjust the length between 34" to 48", wedge it between your doorknob and floor, and twist the handle to lock it in place. I timed myself - 60 seconds flat on my first try! The thermoplastic elastomer foot grips like crazy on every surface I've tried: tile, hardwood, even thick carpet in my bedroom.

Here's where it gets impressive: When my partner installed it on our front door (tile floor), I pushed with all my weight (and I'm not a small guy). The door frame started creaking before this bar showed any sign of giving! That UL-certified 1-ton strength rating isn't just marketing speak.

The smart design touches make all the difference. The rotating footplate maintains perfect contact angle unlike cheaper ball-joint models that slip. The yoke protects your doorknob finish during installation. And at just over 3lbs, it's heavy enough to feel substantial but light enough for travel (hello hotel room security!).

Now for reality checks: On extremely dusty floors, you'll need to wipe the surface first for maximum grip. And yes - if someone really wants in, they'll eventually break your door frame before defeating this bar (hence one reviewer replacing all his hinge screws!). But that's exactly what you want - the weak point should NEVER be your security device.

At this price point, you're paying for military-grade protection that could literally be life-saving. Worth every penny for the peace of mind alone. Just buy it - your future safe-self will thank you.
