ELEGOO 3Pcs Mb 102 Breadboard 830 Point Solderless Prototype Pcb Board Kit For Arduino Proto Shield Distribution Connecting Blocks One Size 1）830*3

*update* Elegoo very graciously sent me a new set of these and I can confirm that the initial ones I received seemed to be duds that snuck by Quality control. The new breadboards have none of the issues I originally reported, the power bus strips work just as well as my very expensive breadboard and the rest of the bread board holes grip components firmly but without the excessive force that was required on the one I originally had trouble with. Elegoo's customer service was exceptional, It is great to see that there are sellers willing to help their customers when they have an issue! I look forward to purchasing more items from them in the future! I have left the old review below incase another customer has issues that are similar. -old review- Good things first, these breadboards arrived quickly and are labeled correctly! They are labeled A-J on columns, and 1-60 on rows from left to right. The bus bars are continuous and do not have a break in the middle. Now onto the less great things, they seem to have quite a variety of quality between the three that arrived. Two work okay, one has all the pins from row 30 on slightly offset from their holes so that it is difficult to insert components into it. All three have issues with their bus bars, none of which properly grip (in fact I don't know if they are holding the components at all, they may just be resting on the bottom of the slot.) and as such cause huge issues if using them as power rails. Another issue I had was that none of these would attach to the other 830 breadboards I have (one of which was from the Elegoo super starter kit) their clip points were offset from any of the other boards I have and only seemed to be able to clip together with eachother.

Not bad quality

I like the look and feel of these boards. I have a number of boards from different manufacturers and these are easier to read imo. The boards themselves feel better constructed than the others I have. And I have enough of the half-size breadboards and wanted three full size - Elegoo fit the bill and they are a very reasonable cost. Perfect size for my projects that need the full length (for instance if you want to use a BreadVolt to power the circuit using batteries).

Distinguished

Pretty good but had some problems getting pins to stay in for some reason.
