840Pcs Breadboard Jumper Wire kit for Arduino, 14 Vaules, 2 mm/0.08"-125 mm/4.92" Minidodoca U-Shape Magnetic Jumper Wires Assortment kit & 4Pcs 34cm/13.4 inch Length Alligator Clip Test Leads

Upon initial review the kit seems great. Love the organization box and the addition of the tweezers especially for the tiny jumpers.I have yet to use it but from a quality standpoint it looks like everything should hold up. There are no visible defects.

comes in a plastic box as shown. Wires barely ll fit. smaller wires are in plastic bags I guess to keep them from moving around in shipping, and to keep the counts accurate. Each length a different color. the wire size is correct for breadboards. Also comes with a small tweezers which helps position, but not insert the wires. My box lid was warped a little, no big problem.

Nice assortment, definitely saves time. Only complaint is once you take the jumpers out of the bags, their all wrapped up tight to fit in the plastic box, they no longer fit and just kinda spill out and get mixed up.

Excelente lo recomendó mucho !!

The wire used for these jumpers is too thin. The stripped ends are not stiff enough to reliably insert into breadboard clips without bending or folding up on themselves. Most often I have to grab the stripped end with needle nose pliers a few millimeters above the breadboard to get enough stiffness to insert. Thicker wire would be worth twice the price for the time and frustration that would be saved in using them regularly.

The kit is full of pre-stripped jumper wires and also comes with a set of alligator clips that terminate in connector pins. Those have been the most useful part of the set, as it allows me to easily hook up a battery to a breadboard.

exactly as described, well packaged, arrived quickly, used at a hackathon
