These breadboards are four or five times the price of the far more common cheaper alternatives, but they're well worth it. The spring contacts are far better and more positive, making it much less likely that wires will accidentally pull out, but more importantly, they seem so much more reliable. Failed contacts on the breadboard itself are difficult to troubleshoot and this one just doesn't make mistakes. The makers say each hole is good for a thousand operations, and I haven't reached that, but I have reached well past the point where cheaper breadboards start giving trouble and it hasn't failed. The time and aggravation it saves is well worth the money. The larger the board needed the stronger the argument to get one of these.
