Great quality, great price, and very helpful for my electrical projects.
This has allowed me to prototype so much easier. I was able to take my projects to the next level and make it look clean while doing it. I love the variety of sizes and how much of it you get. The case is also good quality and sturdy. The wires are soft and easy to bend but not just flexing all over the place. Great price as well. I will definitely buy more when needed but I have enough that I should be good for a bit, which is lovely.

Good stuff
I greatly prefer using these instead of the standard wires that poke into the breadboard and loop from hole to hole because when I'm done prototyping, I can see and follow all traces pretty easily making it not just look a whole lot better but making troubleshooting far easier. These are nice wires - insulated just to the end where it should be. They are stiff enough to get into the holes and bend just how they should and are color coded by length. They really are about like many other brands. I bought because of the good price and the nice case. Highly recommended.

Nice quality
good resistance and good quality.

decent jumpers, could be stiffer for forcing into breadboard holes, but work fine.
they're wires, in specific lengths, relatively easy to use. knocking a star off because they're a bit too flexible, could be a bit stiffer.... and doesn't even need to be a thicker wire, just a stiffer plastic on them would also help.

Perfect for the engineer with OCD
I LOVE THESE WIRES!!! I use them in my digital logic class. They are very sturdy, I haven’t found a bad wire and there are plenty to create any circuit you want! The colors are very helpful. I use them with breadboards and they work perfect! Like me in the study room, they lock in and don’t come out.

Good Length, Not Very Sturdy
The jumper wires are a good length, but not very sturdy. Tweezers included are a bit flimsy. Still works fine for getting the job done.

These are at best extremely frustrating, and at worst absolutely unusable.
These jumper wires are made of soft aluminum. Difficult to get to go into the solderless breadboard holes enough to stay there. Also they will not take solder, so using them on the solderable mimic boards to make a successful design permanent will not work. Further, they do not follow the electronics color code like all others I have used in the last 50 years. Same colors, but don't match the jumper length. It is also just annoying that they are apparently manufactured in millimeters while the breadboards are in inches. The resulting labels are in decimal inches. Let's see, for 5 hole spacing (5x0.1"=0.5") , do I use a 0.47 or a 0.59?
