I bought 2 of these basins to go with 2 different rain chains. They are worth the money for a couple of reasons. First, he company provided a 1’ long copper chain that fastens underneath the basin and runs through a hole up to the bottom of the rain chain. I needed the extra length because both rain chains were 8.5 feet long while the distance between my gutter and the ground was 9.5’. I thought I would have to buy extra chain but it wasn’t necessary because of the 1’ of copper chain provided with each basin. 
Second, he basin is also large and heavy enough to weigh down the chain and keep it from blowing around in light winds. It’s windy where I am so I put a mid-sized rock in the bottom of the basin to keep it from blowing in high winds. But the basin is substantial enough most of the time. 
Overall, it’s a good product and it matches both rain chains.
