These are good for what they are, which is a strain gauge that isn’t super expensive for lab work or something like that. I’ve checked several gauges and the ones I got all seem to be right around 121.2ohm, I’m just guessing but maybe they are gauges that didn’t make a 1% tolerance to 120ohm so they get sold on Amazon as off brand for cheap. I’ll take it! They are at least consistent so that’s all that really matters for my use. I’m only writing this so you know and maybe double check the resistance if that is important for how you plan to use them.
