Rated 4 out of 5 by from Budget price A reliable lock for a budget price. Fairly straight forward to re code (not for the DIYer) Needs to be installed accurately to perform smoothly.

Rated 5 out of 5 by from Good sturdy lock Good quality lock, feels sturdy and is designed for outside apparently. Want to see how it holds up after some bad weather but i’m sure it will be up to the job.

Rated 3 out of 5 by from Inaccurate Instructions It works fine, eventually! I used it to replace an existing internal door handle. The new latch simply replaced the old one. 3 additional holes required so nothing too bad. The big problem is with the instructions to set the code. The instructions don't match what's in the lock so they make no sense. You need to work out, in my case, that the red tips need to go where you need the numbers included in the code. 1 hour to fit, more than that to setup due to poor instructions.

Rated 5 out of 5 by from Best lock Very reliable lock works fine. Still works brilliantly and heavily used a present. I have managed to get much cheaper in Screwfix. Staff always helpful, if not in stock ordered in and is there for the next day.

Rated 5 out of 5 by from Number lock Easy to change number if you follow the instructions I found a pair of long nosed pliers best to remove and replace the parts. Easy to fit replacing an existing lock in under 5 minutes.

Rated 4 out of 5 by from Good value, good item. Was pleased with the unit so I bought another one. Relatively easy to programme, I need a small pair of pliers to assist with this, spend a few minutes reading the instructions and it is easy to install.
