"Just fitted this to an external timber door so can't comment on reliability but it looks and feels well made and comes with really good fitting instructions, including a template for the door and frame cut outs."
"I have used these before and know they are good quality. You can get much more expensive locks, but I can't see what advantage they are. This is 5 lever, as are most of the expensive locks. I have fitted quite a few locks in the past and know you have to have the right tools to do the job and the time to get it spot on."
"You get what you pay for and this is not bad value for the price. However, the first one I had to take back as it kept jamming and the replacement had the latch on the wrong way. But it works and is fine for an internal door. As usual Screwfix staff always helpful when dealing with these issues"
