Based off history it should go back down.
Is it that good quality to be worth 70-100?
Considering 16 gauge ones can be had for ~$40 (or less if you get a deal), it’s probably for high-powered equipment. The higher the gauge, the thinner the wire.
You can’t get this spec for $40, but I’m not sure it’s worth paying the premium if you’re budget conscious and don’t need the extra features (lighted corner, jacket, strain relief, lower gauge, etc).
