Very sturdy heavy duty lock system. A lot heavier than I expected it to be but that is boy a bad thing. Pretty easy to install. My husband was able to install it without any professional experience or assistance needed. Took 20 minutes to install. Great security features and works great. Makes me feel like my home is now much safer and secure. Nice color that goes well with any home or door I would think in my opinion. I would place this lock all around my home if I could. Easy to lock and unlock without issues or sticking.
