Review on 🔌 Optimized Low Voltage Wire Splice Connectors by Jesse Francilme

They seem good but advertised for 24 gauge which is what I want. They have 0.5-0.75 printed on the top of the T (you can just make out 0.75 in the seller's photos). Assuming that it is a metric designation, this means 20 to almost 18 ga. The bottom of the T says 0.35-0.5 which means 22-20 ga. So what it really means is the connection of 22-20 with 20-19. Xian Chong also speaks there and gives the specified voltage/current characteristics.
