“It's great! Easy and fast. Check a video in Pimoroni or YouTube first, to check how it works. You can save money and time buying headless Raspi Zero and avoiding soldering with this!”
“I'll agree with the reviews that it's difficult to apply these without the plastic supports (but the flat end of a chisel worked well enough). Works great with my Raspberry PI Zero.”
“I've bought two of these, the first went into my Pi zero perfectly, the second took a lot of hamering (using the optional jig) into my Pi zero W and still isn't all the way in, but it's gone far enough in to stick and be useable. Still, it's far preferable for me than soldering 40 pins!”
