These are good quality IC test hooks with a male connection wire. Instead of a single hook, these have two hooks that are capable of grabbing very small points (like SOIC IC legs). Comes in a bag of five IC hooks of different colors (black, red, white, blue, and green). We use them with the Bus Pirate logic analyzer harnesses but are very cool on their own.
Wire length is 2.5" long. Male pin easily inserts into breadboard or other standard 0.1" connector.

The hooks are so weak that the tension in the pig tail end is enough to break them loose. If you hook them up and then move anything in any way, they will come off whatever they are hooked to. It is way too frustrating for me to have to gingerly connect them and then make sure I don't even bump the breadboard the pins are into for fear of having to reconnect everything again. I would rank them as one of the very few products I have been dissapointed with from Sparkfun.

These little IC Hooks are great for doing prototyping and hooking circuits on a breadboard to things I don't have headers on. They are a little cheaply made though. I'd like to see SparkFun come up with a better quality item. I'm ordering more for now to get me by. :o)
They do the job. Could be cheaper, but this isn't a bulk order kind of business.
Makes it easy to monitor IC pins.
They work well for my needs. They are small, and thus delicate! Treat as such and they should work Okay until even smaller ones are required!
They will grab 16 - 24 AWG wire reliably, but if you use ~30 AWG you'll have to take some extra care. I think the target market here is 0.1" pins, and SOIC packages. It would be nice if Sparkfun carried something of better construction in the same format.
It's hard to complain very much because even pricey logic analyzers seem to skimp on these things. Soldering a pin/wire it's attached to will deform the tip. No cracking or splitting or gold flash wear problems after ~1yr of infrequent use. Sometimes re-situating the attached logic analyzer will pop them off, or put undue strain on the DUT. A highly flexible lead wire would fix this. Grabbing to release at an off angle is virtually impossible because the bumps aren't grippy enough. A design with 360deg features could solve this (think miniaturized oscope probe tip).
High Temperature Resistance: Poor Tip durability: Good Flexible lead wire: Okay Convenient release: Poor Contact reliability: Good Compatible wire gauge: Good (14-30AWG by my estimation) Color selection: Good
