I ordered this item as our previous lock had started to play up. It arrived very quickly and very well packed.

Instructions were very clear, and in a few minutes I had successfully removed the old lock and replaced it with the new one. Since the new lock has been fitted it has worked perfectly, without any problems or issues. It looks to be a very well designed and manufactured lock, and it feels as though it will give us better security than the lock that it replaced. All in all a very good value purchase and well worth the money paid for it.

Got this for a patio door that needed the shorter length lock. Fitting same as most Euro cylinders, just unscrew the bolt and slide out the old lock then slide in the new one. The new bolt was a bit long so used the old bolt as it was the same thread size. The lock seems solidly made. The Cisa keys are very secure with 10 pins in the side of the key. Have had no issues with inserting or turning them. As the keys are straight sided they are less likely to rip a hole in your trousers.

I've used these locks before on previous properties and have always been happy with them. I chose 2 barrels with 4 keyed-alike keys. All work perfectly and I'm happy with the increased security they provide.

Fitted in 10 minutes,no problems at all,security side not tried,no one attempted to break in yet,but it appears a solid lock,it was suggested to me by a retired locksmith.

The cost of the lock was very competitive,no problems with delivery which was fast considering,problems with Royal Mail.

Would have no hesitation in recommending both Safe as a company and

Cisa as a brand if looking to replace a lock.

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.

It was easy to fit, normal Euro lock fittings.

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.

The cylinder was a perfect fit, flush with my handles both sides for added security and assists in preventing cylinder snapping.

I have used 6 pin locks in the past, but this is a totally different product. The build quality is good and there is no possibility of "picking" it like with a standard Euro lock so I'm totally satisfied that the small price difference is worth it to upgrade the security to this level. Fitting is extremely simple and it can replace any standard Euro lock in less than 5 minutes, so totally happy with this purchase. Safe is the best value place to get them as well.

I really like these Euro cylinders, I've had them for more than 10 years without any issues, in fact the only reason I've ever had to change one is when I lost a key. The lock I removed was perfect after a number of years service. They are easy to install, easy to use and give good hard wearing security. The only improvement I've seen is to include a magnetic element to the key and lock which is maybe something you should think about. Anyway be assured, I will buy this system again for future doors.
