This helped a lot as I experimented in getting the right resistance and configuration. I needed to fit the components into a tight space so this was great for trial and error

I've been using these for many years without issue and have around 200 of them.
This is the one you want

In most cases... If you look at most schematics, about half of the components have a connection to rail. Therefore these ones with 2 rails next to every row of uncommitted contacts is going to be the best to use. For the money its acceptable to consider them as single-use breadboards, cheap compared to any other prototyping means. However, they are totally re-useable.
I wouldn't expect any of these types of breadboards to be reliable forever, none have gold-flashed contact surfaces, but that's the point isn't it - they're a quick breadboard to get you started.

The quality is fine, and for the price the product works very well.
