Set up was super easy. Most of my time was spent unwrapping the lights and wrapping them around the trees. It arrived with some charge, so I was able to test the different modes and set it to what I liked so it would be ready to go that night. All of the bulbs worked perfectly.
The stakes are long enough to dig deep and keep the trees securely in place. I have harder soil so I only dug a few inches, but they've been fine even in some light wind. There is plenty of wire between each tree, so you have flexibility on how far to spread them out and fit them into your design.
I ended up placing them somewhat close together along the entrance to our yard. From a distance they look like small bushes and don't look out of place during the day.
