Great kit, excellent for learning electronics and really fun to make. It is also useful. Fast shipping. I upgraded it adding a micro USB port to power the hourglass instead of two cables.
High quality PCB, all parts in the package and works fine immediately after soldering. Highly recommended.
Easy to build, max time is about 80sec, very bright LEDs 🙂
