They work great with my 1/4 inch breadboard. This makes them stronger than the usual two-pronged connections used by cheap tanks. They are strong enough to withstand anything that fits inside them. As a test, I came up with a way of hanging a 10lb bag of flour from one of them using a bungee cord and it held up! I wouldn't recommend packing that much weight in it, if at all possible, but I was impressed. I would recommend them to anyone who has a 1/4" pin. It looks like they might work with a 1/8" board too, but I can't verify that. Feel free to order. If you want something better, you probably shouldn't be using board-attached containers.
