These are ok.  At least for us, they don’t always latch 100 of the time.  The other standard pocket door locks were definitely worse (these are an improvement), but you still don’t feel secure unless you live in the home and are used to the little quirks (make sure you twist it all the way to the left and then a little extra tweek for it to latch, door has to be lined up properly).  Many times I’ve opened my 7 year olds bathroom pocket door and she thought it was locked.
