Sagging front door. Did the lazy "drill the catch hole larger" hack. Worked for a while, but eventually a five year old putting her weight on the door handles and Christmas wreaths clogging the door jams got it to a point where I needed to address the sag. I was skeptical, but figured I could always return it if I really needed to replace the latches and deal with realigning everything. But it worked. Not as well as taking the door down, replacing the hinges, and dealing with realigning everything. But still, it worked. At $22, the price is a bit steep for a single purpose tool. And if the pin remover was separate, that would have made removal easier - as it is, it's just added complexity and likely production cost. But if you value time over money, this will let you fix a sagging door in minutes and get back to watching the game versus spending all day dealing with the not fun task of replacing hinges.
