The handles themselves seem nice and feel sturdy (Time will tell) but the common method of installation (Especially for the home handyman) is to use a jig. These door handles require the holes to be no larger than 50mm whereas every jig I could find in Australia is for a 54mm hole. Fortunately there is another way to install them but it does require drilling 5 small holes instead of just 1 large one. We will be buying more handles though so overall we like the product.
