SunFounder5PCS Breadboards Kit Include 3PCS 830 Point 2PCS 400 Point Solderless Breadboard Compatible for Arduino Proto Shield Distribution Connecting Blocks

I bought these for a quick same-day weekend project. They were functional but I found they gripped components very weakly. If you just need to wire a few relays into your arduino, or make a flasing light or such they'll work, but I wouldn't expect to still be using them in a year's time.For professional prototyping a firm grip with ultra-low impedance is critical and these simply aren't well-made enough for that, but then they're 1/5th of the price. If you are serious about your work please take the ultra-positive reviews on here with a pinch of salt, do yourself a favour, and just spend more. Myself I threw these away once I was done with them and bought a known brand as I should have in the first place.

I tried many different breadboards, including the popular Elegoo breadboard, which I have to say was the worst experience, I almost broke my ESP32 trying to get it out of the Elegoo breadboard. These breadboards are perfect, they are not too tight but not loose either, works great with wires and micro-controllers as well as ICs. After trying multiple beadboards, I am settling for these as my go to. I highly recommend these breadboards.

I use these for prototyping hardware, they're useful for testing modules or IC's.There are multiple rail "bars" which allow you to tap your supply off as needed, you'll need a pack of jumpers to go with it, but they are a useful addition if you're into electronics or just started learning.

They are breadboardsCheaply made with metal that deforms after placing some kinds of components onUnless you need several breadboards for a project you would be better off getting a single 400-pin breadboard for the same price but better qualityThey are an attractive option for hobbyists who are just starting out, however you do get what you pay for

Not particularly impressed compared to other boards that I have. Some rows so stiff that the conductors/grips push through the backing. Also the plastic links between board and power rails very flimsy so difficult to attach multiple together.They'll suit my immediate needs but as another reviewer noted, I don't expect them to last long.
