"A good piece of kit, but a bid fiddly to get the two halves of the lock lined up when installing - a couple of mine are about 1mm out and rub when they close. I'm sure I could correct this, but I don't use those windows often. A bit more tolernace in the design would help the less accurate installer out!"
"Absolute nightmare to install. If not completely aligned, it won't encourage use as it is poor design. I saw a similar review before buying but thought I could manage fine. WRONG. Had 3 attempts before making it just about work.
Was going to buy bulk, 10, but thought better of it and bought just the one. Thank God. Have to buy something else.
"Well read the last review and thought it might be the guy who just couldn't fit em (Sorry) Well how wrong was I utter rubbish poorly designed 1mm out and they will not fit, has too be that close to window seal I also question security One would not close after fitting and a slight twist with a screw driver snapped the thing in half. COULD BE THE WORST THING I HAVE BROUGHT IN YEARS!!!"
