Good solid product
Easy to install, looks great. Especially handy to get all 5 deadbolts keyed alike.
Looks great and easy to install
CA Landloard
The locks look just like the picture and were easy to install. They are sturdy and look great. I bought three and had them keyed the same with 2 other handles for my rental. All locks easily open with the same key. Cheaper and easier than anywhere else. Will purchase again when the rental becomes vacant again so I have another set to use.
Very secure and tight
