Tried to open the door without noticing that the chain was on and the chain came clean off the hanger in just one pull. Do not buy this if you value your safety!

Did not look nearly as shiny and new as in the picture. Not Chrome at all despite the description. Doesn't look like the picture at all.

Looks Nice, Good Quality for the Price
I installed this in a rental property to give the tenants the option to have extra security. It was inexpensive compared to others, looks very nice on the door, and does provide some extra security. If it was in an extremely high crime area and I was terribly worried about people trying to bash my door down I might have spent more for a heavier duty one, but for most people's needs, I think it's perfectly fine and there's no need to spend more.

Good price and sturdy. Not very stylish, but its great for what's intended for... Maybe the chain could have been a little longer, but not sure if it had compromised it's integrity though...
