Smith & Locke Tubular Mortice Latch Electro Brass / Satin Chrome 76mm is rated 3.3 out of 5 by 11.
Rated 1 out of 5 by from What was different about mine? Mine must have been different from other reviewers. Very poor quality. Slider could only be persuaded back into the tube with a bit of fiddling and when mounted in the door it just jammed. Had to take it back and replace with the Union one. Operation of this one is much smoother and it has a ten year guarantee, but it doesn’t appear in the paper catalogue and is mostly next day availability. It isn’t obvious from the catalogue, but the S&L one only turns one way so not really suitable for use with knobs. And the plastic backing box shown in the picture was missing.

Rated 2 out of 5 by from Wore away radically in a year Sold as suitable for domestic and commercial situations. Ours is a commercial environment. Was very happy initially, but one year on I've had to replace it. The latch piece had worn to about two thirds of its original size (fitted properly with the parts supplied used on door jamb) and the internal mechanism had given up in such a way that the latch was extending further than it should and kept jamming. It was fitted to a door that is used a great deal. But cheaper options seem to last as long in this particular situation.

Rated 4 out of 5 by from Solid mortise latch Does the job perfectly replacing a nasty rusty latch. The choice of chrome or brass is a great feature

Rated 4 out of 5 by from DIY Reviewer Bought these in the past and they were great as they have a double spring so work well with heavy handles.

Rated 4 out of 5 by from Very good door latch Very good value for money, easy to fit, good quality. Only just fitted so can't score for reliability.

Rated 3 out of 5 by from States Smith and Locke,but dou Got the bracket and lock set as especially wanted Smith and Locke hinges ,but upon opening pack found hinges were made by Eclipse.On checking cost and availability of hinges the Smith and Locke were dearer but available ,so couldn't understand how each S and L pack contained the cheaper Eclipse hinges.

Rated 2 out of 5 by from Failures can be damaging I purchased 5 of these double sprung tubular latches for 5 new solid oak doors a couple of years ago. One of these latches has just failed and caused a LOT of inconvenience, but it could have been much worse. The latches are solid, have a bolt through facility (great for larger handles), however, they also have a reversible bolt as the latch has to be fitted one way and the bolt turned through 180 degrees as required. The faceplate then holds the bolt in position, preventing it from twisting. On our hallway to kitchen door, the most used of all the doors in our house, the bolt had come loose meaning the faceplate no longer held it in place, allowing it to twist. This happened while the door was closed and it was impossible to open. Fortunately, we were able to exit the house through a front door and get into the kitchen a different way, then get access to the latch from the inside and straighten the bolt. Had this issue occurred with ANY other door in the house and we would have had to either break the door down or break a window - not what you expect to have to do due to a failed door latch! When I purchased these latches they were branded as Eclipse, now they are sold as Smith & Locke. I purchased another one from Screwfix thinking I was getting a different brand, but they are identical, only the name has changed. Of course, now that one has failed after only 2 years, I'm expecting the others may also fail so I'm looking for a better product to replace them before they cause further damage. If it wasn't for the rotating bolt, these would be great latches.
