Functional but not carefully made. A couple of the blocks are a little cockeyed.

Already the berg pins were soldered and it's working with my Arduino as expected. They can at least provide different colors as an additional option

I was looking forward to this, based on the user pictures posted. I really need Amber/Orange, not red, and the pictures posted at the time of my order were perfect. But I got red. :( So it's not useful for me. Seems to work as expected, but it's the wrong color.

I just wish it was a 4 pack so I could make an even 1x4, 4x1 or 2x2 stack of them as one big display the only option here is one wide line or an awkward 1x3 stack which results in 3 rows of 4 columns just roughly too small for an extra row of usable font but not small enough to evenly place he desired font center. I’m thinking I’ll use one for a separate project and 2 stacked on top each other for a single large line or 3 medium line display

There is a very small gap between each module, not sure why they aren't butted up right next to each other which would make it seamless. Other than that, the module works great.
