Nice size breadboard for 2+ microcontroller projects, components, etc. and a nice price! One thing to note: (the product photo here is somewhat misleading) ...this breadboard is actually broken up into 2 different power distribution sections. If you want to supply power to the entire bread board with a single power supply, use jumpers to tie the power rails together. This worked well for me! I have two PICAXE 20M2 microcontrollers [RB-Pic-31] and a 315MHz transmitter [RB-See-11] all working together on this bread board [RB-Cix-10] with no issues! I use the SeeedStudio Breadboard Power Supply [RB-See-93] to power my projects using USB power from a laptop.
