Realistically, everything is finite use if you can’t maintain it. The more relevant approach is what kind of utility do you get during that thing’s lifetime, and does it outweigh the other options. NVGs, while not my choice, do provide a lot of utility, and last a fairly long time. They also don’t run the risk of full-on breaking, just running dry, meaning that they can be kept around if you think you may find batteries.
