SE Clip Test Lead Set (10 Piece)

These are absolutely the worst leads I've ever seen. They prove that the "cheap overseaas" moniker is deserved and --astoundingly-- devolving. The wire is maybe 28 AWG, _maybe_. It's uncoated copper, pre-corroded (turning green/black). The plastic coating is a bit rougher (which initially seemed nice, versus the previous el-cheapo leads with shiny plastic coating). The clips are of course awful. The clips are crimped (not soldered) onto the wires and coating, with the bared wires folded back over the coating...meaning that simply "adding a dab of solder to the crimp" (which used to work on all previous el-cheapo leads) no longer works and instead causes a molten, stinky plastic mess.

Beware this product; they've actually made what was already horrible much worse. I'd send them back if it didn't cost more.

I find my opinion of Amazon decreasing as I discover they carry such total garbage. And the clowns who write positive or blaise or non-critical reviews... Read more

These jumper clips have the thinnest wires I have ever seen, probably 24 or 26 AWG. The wires are so thin they feel like they might break internally or disconnect from the clip ends. I was hoping to toss these in a toolbox for frequent use but they would probably be damaged.
If you are going to use these on a bench (for example with a breadboard) and always handle them carefully then they will be acceptable. For more real life use where they might experience rough handling I wouldn't recommend them. (FYI I ordered from Amazon)

Some of the specs on these leads (from the package):

Length: 19 1/2"
Alligator Clip Length: 1 1/2"
22 ga Insulation for protection against shorting and shock
Assorted colors: red, green, black, white, and yellow

These Chinese-made leads are very light duty becuase of the wire gauge and length. Much more suited for circuit board work than for automotive applications where you are possibly handling higher current loads. At 20 1/2" long (measured clip end to clip end), you can't span a very long distance with them and the small clips are barely big enough to grasp connections 1/4" in size. Two leads of each color are included. They are fine for low voltage apps and short jumps; buy something with a heavier gauge wire and bigger clips for automotive work.
