Since I started using Cisa locks at the University I worked at, I have now installed them on all my house locks. Keys are so much more secure than standard Yale type and not orientation specific, which is great when having cold and or wet fingers. This Euro lock took just a few minutes to install.

I purchased this CISA Astral S - Euro Double Cylinder 45 - 50 for our porch as we got already several CISA Astral S cylinders on the external doors. The ones I purchased before are very good ones, but the newly purchased one was not build properly, as if the key is inserted all the way (as usual), you cannot turn it! You need to leave a gap of approx 1mm in order to allow the key to turn and open the door. Same problem on both sides of thy cylinder, quite disappointed.

From the hundreds of cylinders available from Safe.co.uk, this was the only one that had the exact mix of features I was looking for. The main ones being; a higher than normal level of security and usable from both sides so you can't lock yourself out if there's a key on the inside. There were some other features, which I now can't remember. But the filters/wizard made it super easy to find which features were available and to eventually settle on this cylinder.

I choose keyed alike, so they did take a while to arrive (as advertised). Very happy with the product and the service. It's not the first time I've ordered from Safe.co.uk and I'm sure it won't be the last.

I think I also emailed them with a question and they responded quickly and with a helpful answer. Recommended.

Much better value for money, built stronger. Keys are made individually .makes you feel safer.it is a brilliant sturdy lock.i have recommended you to lots of friends.

I was greatly impressed by the various reviews on the Internet and other outlets I had checked prior to purchasing your product. The beauty of the security locks is the immediate impression they give of security and strength which is obviously apparent to would be burglars. We have had great peace of mind since they were fitted and I have not only recommended them to my family and friends but I actually fitted a pair of your locks in my next door neighbours house. I cannot thank you enough for having such a secure and safe product easily available and simple to fit. It was certainly money well spent.
