It would be nice to have a longer hook.

After a few months it started getting to the point of needing to flip the lever multiple times before it actually latches. After about 8 months it has stopped latching entirely.

Get exactly same number of the one you replaced. Others are close but do not work. We dropped the old one down inside the door and tried a heavy duty magnet on a string to retreated it. It was like fishing, took a while. After I got the correct replacement it took 2 of us to install new one. One person to make sure I didn’t drop it again. Works great now.

Though the listed dimensions claim to be the same as my existing lock they are a little off. The top hole didn't quite line up for the handle screw and the face of it is slightly too wide to fit in the door cutout. Because of this, the whole lock housing sits inside the door a bit instead of being flush. One thing not explained in the product description is that you engage the lock by moving the locking lever up instead of down. Flipping the unit upside down would not work with my door.

Good replacements pity they are not made from stainless steel as I live near the sea and I need to replace then every 5 to 6 years. Good solid product does the job.
