RadioShack is starting to get some nice products but sadly, they are not well described on the package or on the web site.  I took a leap of faith and purchased this test lead set and I'm quite pleased with it.  The set is called a "Micro-scale Test Lead Kit" part number 2780039 and costs $20.  The package has a little information on it but it's lacking in details such as what these leads are supposed to connect to.

Let's start with the first question.  What is the lead connection?  The leads are designed to fit standard test lead probe tips.  Personally, I would have preferred that they fit banana jacks but this is ok.  The picture below shows the set.

From top to bottom, the leads are:

• Alligator Clips
• Nano Grabbers
• Micro Grabbers
• 0.025" Square Pins for header connectors and breadboards
• Needle probes (protective cover is on)
• 0.04" Diameter Sockets (which fit DB-connector pins)

On the side are:

• Magnetic Probe
• Battery Insertion Probe

All of these can be handy at times and can save a lot of frustration making connections.

The magnetic probes work great for quick battery connections.

The battery insertion tip is designed to be inserted between two batteries in a holder so that current can be measured,  It's shown below with test leads connected.

Since the manual isn't available until you open the package, I've posted it below.
