2.54mm Mini Jumper Connector - Black (50-Piece Pack)

Pros: Small and compact, durable (tried to rip the metal part from the plastic - couldn't do it). Also pretty cheap,

Cons: Nothing to complain about, Maybe 50 pieces is too much, because I have no idea where i am going to use this much.

Other: Worth buying if you need MUCH of these little guys. If you're an electronics hobbyist, I recommend you to buy these even if you don't need them at this moment, because you WILL need at least one of these later.

Pros: both holes are through. good for my 5mm. leds series circuit. this jumper help me for quick changing bulbs. easy for series circuit (just gule it to a stick and put led bulb in), not need to soldering many leds to small pitch board.

Cons: nothing much. but it will be more better if the body hes long tail for easy put in and out from board with manycomponents.

Other: perfect for normaly use in 2.54 mm. pitch pin board.

Pros: Durable, cheap, well made. Good fit. Does not comes loose. Notch in the middle makes it so much easier to pull them out.

Cons: Nothing wrong with the product. But 50 pieces isn't that much, pack of 100 would be more appropriate.

Other: If you need them, buy them. Good product. Invaluable for the electronics hobbyist, for altering development board connections, changing settings, etc.

Pros: Very useful. Can be used on standard 10mil pin headers. They fit really well, it's easy to insert or remove them, but they don't fall of themselves. The price is good, but the quality is even better, extremely good for DX standards.

Cons: None, really.

Other: Buy it if you need them in an electronics project, there's really nothing which could speak against it.
