These are decent quality and great value for the price. I like these because they are nice and flat and the sockets accept a decent range of wire. They provide growth and expansion to my arduino activities. I purchased these for a school project.

The boards lay perfectly flat and interlock without any problems. Arrived undamaged, no immediately noticeable issues. Hole spacing and labeling (mentioned in bad reviews) have been fixed.

They grip loosely on the first large breadboard i tried. These are almost impossible to use with microcontroller breakouts that are 10 to 20 pins per side. Some holes are very tight, but most of them are too loose and cause bad connections making trou...  Read More

They make prototyping more enjoyable. They can carry more juice than any sane person would put through them. Only downside is the container was all mixed up.

The box is subdivided in the same way as my old kit. The color-coded lengths are consistent within each kit. Stiff, solid wires in a good range of sizes.

Some people complain about solder not sticking. You just need to be good at soldering.

Using these is a tedious and time-wasting endeavor. Spring for the $5 pricier brand and avoid these. These are way too flimsy for breadboard use.

Wires bend when inserting into breadboard. These wires are too limp and flexible to push into the breadboard holes. There will bend & curl up rather than * the holes.

These are tinned soft copper. Either the wire is to thin or it is aluminum.
