4PCS Breadboards Kit Include 2PCS 830 Point 2PCS 400 Point Solderless Breadboards for Proto Shield Distribution Connecting Blocks

Good value for your bread 😉

Good quality I recommended

Must have for the price. Although these may not be the top line proto boards they just work - I've ordered these twice now for an ever expanding home automation project. The half-size boards are perfect for an ESP32 board and sensor.Note that the power supply rails can be easily detached from the main board if desired. Recommended!

They boards are designed with cheap plastic dovetail pins meant to hold the rails together, but the plastic is so soft that they just deform and pull apart. The manufacturer has tried to solve this by sticking a giant adhesive pad on the back to hold them together, which works, but absolutely would not stay together without that pad.With all that said, they still do exactly what they need to do. I've had no dead power rails and all the connections seem to work fine. The size is standard and I've had no issues with pins, and I was able to rearrange the power rails in a convenient way.They're also not very flat, but it doesn't affect their use at all. Definitely works just as easy as any other breadboard. If you're looking for the best-of-the-best, this probably isn't them. But if you just want something that works, this does that just fine.

Excellant for breadboard parties.

These are excellent breadboards for the money. They tightly hold on to inserted wires and components, but not so tightly that you think you'll damage the component with the amount of downward force necessary. These breadboards, available through Prime, are an incredible deal. They're cheap but, if there ARE any corners cut, they're not at all a hindrance to the overall quality and usability. These breadboards are a high-quality prototyping solution for both novices and experts alike. I have yet to come across any issues with the product that necessitate a refund or replacement. The only real issue I had with the product (though it's not really an issue at all) is the quality of the foam adhesive pads on the bottom of the boards.I've never been one to actually use the adhesive foam on the back, instead opting to remove it entirely and clean the base of the contacts with 90% IPA. That said, removing the adhesive was unusually easy in some places, but stuck to the board in others. This isn't a complaint about the areas that stuck, but rather the areas that came off with little-to-no force. I imagine this would be problematic for those who intend to actually mount their boards to something, as it seems with just a bit of humidity and time, they [might] fall off whatever they're mounted on. That said, I live in a pretty humid environment, so who knows how much that factor played into the ease by which the pads could be removed - the product sat, removed from its bubble-mailer/box, on my desk for a week before I had a chance to truly work with them for an honest review.Overall, they're breadboards - and inexpensive ones to boot. They're likely to be exactly what you were looking for at a price you didn't expect would be so low. Again. user results may vary in terms of how well the adhesive sticks, but contingency plans are always good to have. Fail to plan, plan to fail. The mounting tape can be had at any major hardware store for just a few bucks.Enjoy!If breadboard adhesion is mission-critical for your project, I'd suggest applying your own ESD-safe mounting tape. With the money you saved buying THESE boards instead of something significantly-more expensive, you'll still end up saving money.

I was skeptical when I first unpacked these. It's been forty years since I've done any breadboarding and I recalled the breadboards I worked on being considerably more opaque. When I turned them over I was pleasantly surprised to find that they were adhesive backed. That would certainly come in handy. Further examination revealed tabs that allowed matching breadboards to connect together. Great! And as an additional unexpected bonus the rails are detachable; a feature I was not accustomed to forty years ago.Next I checked the breadboard sockets against pre-formed breadboard jumper wires and they held snuggly. Next male flexible breadboard jumper wires were tested and they too held securely. Up next were JST-XH male pins and female connectors-again success. Then Dupont male pin connectors and row connectors were tested with great results. And finally a couple of DIPs were tested and they too held snuggly.I am very pleased with these solderless breadboards by RexQualis. They have exceeded my expectation and undoubtedly will more than meet my needs.I plan on using these in prototyping a four head automotive camera that will have two forward facing cameras providing a panoramic view, a rear facing camera and a cabin camera. The adhesive backing will be convenient for mounting inside of a 3D-printed project box while prototyping and testing. I am also looking forward to using these in numerous Arduino and Raspberry Pi projects.I certainly recommend the RexQualis solderless breadboard for everyone looking for a versatile breadboard for their projects. Get them now before they are gone.

I have found that these breadboards maintain good connections for a wider range of wires. These are now my favorite breadboards. Especially for very small demo/training projects with ESP32 microcontroller boards.
