“The SIL (Serial in-line), connectors are a very tight fit. Once an item is attached it's very difficult to remove. ZIF sockets would help but would increase the cost and size. A parallel lift lever would be a useful accessory. Additionally, mounting holes to enable fitting in a box would be useful.”
“This is an easy way to connect two add-ons to your Pico. It is of good quality, and does exactly what it claims to do very well, so it gets 5 stars. The only negative is that if you do connect two add-ons, you lose access to the Pico pins. Perhaps the pins could be brought out to a double row of closely spaced female headers or something? It would make it a bit more flexible for prototyping without adding much to the cost or size.”
Ahoy Jim!
You could fit stacking headers to your Pico if you wanted a set of socket headers as well?

“Excellent - can use a couple of Pimoroni's "packs" with a single pico or use a single pack whilst still having access to all of the Pico's GPIO pins. Simple, well made and inexpensive. Pretty essential if you've got a pico and even a single pack.”
“So you have a Raspberry Pico and it has soldered headers which means you can connect things to it, but that means leads flying all over the place and there's a danger of the header touching something it shouldn't and causing a short or something which could damage the Pico or whatever it's connected to.
Now just plug the Pico into the expansion board and Pico daughter boards can then be added or pinned leaded just plugged in and it feels a lot safer and secure.”
