This just reduces the weight of the food sanitizer from 7.0 to 0.5. It's a tiny device which looks like it could be put on your keychain and even has a keyring attached, so a lower weight seems appropriate as unless the device were made of solid gold or uranium, there's now way an item so small could weigh so much. It's silverish in color so it's not gold and If it were made of uranium, it would irradiate your food rather than "sanitizing" it.

Note: Use FOMM to ensure it is loaded after any other mods that effect the sanitizer's weight, namely MiscWeightFix.esp

This mod does so little, I suggest merging it into another mod w/ FO3Edit {copy as override into ______.esp} to clear the spot in your load order for bigger stuff.
