Unfortunately, you can not really leave here on the reviews, because you do not know what breadboards you get.
I got the boards, where the power strips at a time to go through (plus and minus to go from one side to the other side through), which I find very good, but one star more.
Here are the holders, slightly bent in the holes, thus I get either the parts which I'm trying to put pure not pure, or you do not hold properly. In the picture I once marked ask a few.
I've tried, by force, to get an Arduino Nano into the holes and have managed to connect clips to push down from the board out what does not happen in the expensive.
At a Board were even connect clips, which run in the Board, wrongly reingesteckt thus touched plus and minus and gave a short circuit.
I regret to advise against this breadboards to buy, because it is more of a gamble.
Expensive breadboards and these cheap here, do not fit together well by the anchors at the sides
Even though I might not be here that should, but when you get the expensive Reichelt breadboards for a similar price.
