The main limitation is that each brick likely requires its own power source since no hub is included. This can lead to higher battery consumption if you light up a large area. It is best suited for small accents or single brick swaps.
Buyers looking for a simple and safe way to add color should choose this kit. It works well for parties, stockings, or simple home decoration projects. We suggest it for families wanting an easy introduction to brick lighting.
