I think that it was made more firmly than other companies' bread boards. The price seems to be high. I feel that the size is a little small. For example, when using 48 pins such as PIC, at least two or more are required. If you place a commercially available PIC board (one with the minimum function) on this board, it will not be able to place other parts on it. Also, although the power supply is only on one side, it is only necessary to combine the boards on the side without power supply, but it seems inconvenient that only the power side can be combined with the side without power supply. Trying to form a circuit in a PIC book, it is necessary to have at least 2 and 3 more if it is somewhat complicated. Although it is only breadboard this time, since the tip for the connection of the same manufacturer is also firm and it is possible to arrange it adjacently, it seems that the thing of the same manufacturer is good.
