This is a simple and easy to assemble kit. The assembly instructions and all necessary notes are in the pictures on the product description page; the package doesn't include neither instructions nor BOM. You will only need to buy 3 CR1620 batteries separately, they are not included (the seller warns you about that). It spins well, shows every pattern for a couple of seconds and switches to the next one until you push the on-off button; after a couple of minutes it will automatically switch off on its own.
