Worked well to provide an interface over WiFi to a USB-connected UPS using apcupsd. Booted immediately with 64 bit Bookworm flashed to an A1 SD card with Pi Imager. I first tried an A2 card, which flashed but the Pi wouldn't boot from it.

I’m an aerospace engineer and work multiple projects that my handy Raspberry Pi’s are invaluable. From a quick passive RFID test to a coffee cam (who wants to go for coffee only to find the pot empty!?) with a multitude between. The PiZero is the basic of the basic and it has helped me dream up tons of solutions. Do not discount the fact that this is a cost effective method to tryout ideas!
Vilros is always in stock and shipping is always a breeze!

Got the kit as my first attempt to get into Pi computing. It arrived a few days after ordering, has more things than I need for my application (ADSB receiver). The metal case is solid, and does a good job dissipating heat.
Only gripes: it was a very tight fit getting it in, and removing the micro SD card requires tweezers. Neither are a big deal, knowing the pi is a small device, and in my case it won’t be opened often.
Recommend.

Passive cooling aluminum case is very nice -- very solid. Didn't have a big enough opening for Camera 3, but made short work of that with a nibbling tool. The OTG adapter was a must.

Lots of optional parts for whatever your project needs.
Wish I had bought a few more kits before they became unavailable again.
