Wires are thin and adjustable. Doesn't hold their ball shape unless hanging where there's no traffic or wind.Amazingly bright LED lights and it gives a highlight to Christmas outdoor lightings. Happy with the purchase and hope it will last (not like some other LED lights that damaged by the rain).The lights are amazing, bright & beautifulPlugged in once, worked fine. Plugged in 2nd time - Dead. Controller is bad. I bought 2, so I used the other controller on the string to confirm. Not much confidence this will last long.Just placed another orderJust the right amount of piazza. Just wish they came in a longer length with more lights per strand.Love this lights were just what I wanted for my son he loves fireworks..
