Exactly what it states it is and extremely helpful

This holder is making a great test bed for my projects. I have mounted my Raspberry Pi B+, Arduino mega2560, and the protoboard on it and now have the ability to set up almost any type of test I want.

This board is great if you're using it for an Arduino or RPi Zero but not so great for the RPi 3. Why - because with the RPi 3 the SD-card ends up between the RAB board and the PC board. So to get the SD card out without removing the RPi board you have to use tweezers that can grip and remove the SD card, without damaging it, of course.The other problem I had with this board is that some of the screw liners used in the holes have damaged threads so the mounting screws don't really work. I've had two of these boards and at least one hole was bad on each.Overall I thnk I'm better off just using a small pexiglass sheet from the hardware store and using some small screws to mount the computer boards. If you're planning on having several boards that could potentially bring the cost down to under $5/board, including the breadboard and jumper cables (which can be found inexpensively on Amazon).

Prevents lots of accidents with lash-up breadboards. Really nice quality. RAB holder and T-bone for RPi GPIO breakout and extension cable really needed and handy for experiments and prototyping.

Nice to setup a circuit and keep it together.Note: There are some similar products that do not have all of the mountings or all of the add on (ex. Raspberry Pi breakout board). It worth spending the couple of extra dollars.
