Very fun little kit!
For Forever Flasher kit
I really like this kit! The little ic is challenging, the thru hole components are good quality and so is the board and the battery clip. The lights have a very pleasing short flash and a short round glow spot after each flash. Strong enough to briefly light up a dark room. I look forward to many years of watching it blink. Make sure you write the date on your battery! The QR sticker on the bag for the instructions didn't work but a quick Google search brought me to the assembly PDF so no harm done.

Thanks for the review! Re the QR code, have tested it and it works for me, it might be a phone camera resolution issue so I will look at increasing the flowcode size a little for the next batch. Instructions are also available in the Documentation link in this listing, above.
