Here is what isn't mentioned. This thing is designed to be snapped together. You can take the power rails off of one side and add them to the other or remove them all together. If you buy more than one of these you can snap them together to make a much larger BreadBoard.
Last point, there is a companion SB400, that is a single sided PC board that has the exact same layout as the BB400, so once you have a working design, you can transfer it right over to a PCB to solder finalize.
All in all I'm impressed with the thought that was put into this simple product.
Needless to say, I'll be replacing it with something much more durable and well-designed.
If you buy this (the price isn't bad at all), just don't stick it to anything!
I can't even mark it as a negative because of the functionality, but the side power bands do seem like they come off the unit a little too easily. After I finalize some sort of case design, i'll be gluing them together. In the meantime, the adhesive backing does a good job of keeping everything intact as it is not scored or perforated (read: knife required if you want to remove/move the power bands around). Having both + & - lines on either side really helps clean up the wiring, and definitely makes drafting the schematics a little easier.
All in all, this seems to be the best breadboard I've come across. I'm happy I ordered 4 of them, and I'm fairly confident I'll be looking for this one again when/if I ever need more of them.
**mentioned above another generic ordered, this is the link to it. Bonus for this kit is it includes all the other goodies.

I don't understand this concept of misalignment. It forces one to use different parts than desired when designing a circuit in order to fit the alignment and the parts don't sit nice and straight. It does not really match the SB400 Solderable PC BreadBoard, which, does not make any sense either. Otherwise ok.
Edit: All of these type of boards with the disconnecting edges have been frustrating as they stop working after little use. Get only the ones that are a solid one piece with the edges!
I like the color-coded rails, makes it easy to see at a glance where to plug in without tracing wires. It is a decent size. It is hard to see in the picture, but there are tabs on all four sides so if you have multiples of these you can snap them together into a larger board.
The power rails on the sides also detach from the main part of the breadboard. At first I thought it was flimsy plastic construction, turns out to be the snapping thing combined with the adhesive backing keeping it together.
The only thing this is missing is a dedicated power connector. Some boards have screw-down terminals for easy and secure power connections. Given the modular nature of this board that is not feasible and I really can't say it's a bad thing not to have it. This board is easy enough to power and works great.
