I bought it to demonstrate my stuff at the congress. It's good and fairly durable, but plastic tips can be a real hassle. I recommend Zipties if you don't like connectors. Some of them are difficult to put back on, sometimes you are not sure if they are fully inserted! In addition, the kit includes two different types of cubic wires - 14 pcs. 5x5 and 9 pcs. 8x8, with 24 pcs. Connections. If you want to make something big, you'll probably have to buy two because you'll most likely run out of connectors. 8x8 and 5x5 are different sizes. So if you run out of one and have to use the other, they won't connect well and your dice will be wobbly.
