Let me start by saying this no-drill mount is a game-changer for renters like me who crave security without permanent modifications. I installed it on my inward-opening apartment door in under 10 minutes - no handyman skills required!

The stainless steel construction feels sturdy, and I love how the anti-theft L-bracket cleverly blocks the E340's release mechanism. Though fair warning: if you're using batteries, you might skip this feature as it could complicate swaps.

Installation was a breeze thanks to the included mini screwdriver and door-protecting silicone pads. The adjustable clamps accommodated my 1.5-inch thick door perfectly, and that special steel plate really does bite into the frame when closed - I've tested it multiple times!

Now for the real-world test: After three weeks of Amazon deliveries, pizza nights, and nosy neighbors, my E340 hasn't budged an inch. The camera angle captures packages perfectly without showing too much of my interior when the door opens - though this might vary based on your entryway setup.

The only drawbacks? The all-black color doesn't blend with light-colored doors (a white option would be amazing), and those tiny screws do require careful handling. Also, double-check your door gap - that 0.06" clearance is crucial!

For $25, this solved my rental security dilemma beautifully. It's become my new housewarming gift for apartment-dwelling friends - just make sure their doors meet the specifications first!
