The connectors had two issues which were fine for me but probably not the best in other situations. The top accessory port is extremely flexible. So if used in a situation where there is movement, it probably won't last long before breaking. The main connector that connects to the main source dangles a bit so it could slip off in a vibrating situation. I've used it in a situation where there's almost no vibration and no movement on the piggyback side, so it worked for me, but next time I'll definitely buy something more durable.
