    Great replacement for standard Euro Cylinder. Prevents you ever getting locked in because you've locked your door from inside and then mislaid your keys. A good thing for extra fire safety.

    Good product and excellent customer service. I made a mistake with measuring and ordered the wrong product. I had the product exchanged with no quibbles in no time. Really impressed.

    Really good solid lock. The screw to hold it in place was much longer then the one it was replacing and tightened up the thumbturn too much if it was screwed right in. We used the outgoing screw instead but might be a problem if you are fitting a new lock
