Bought for a basic entry level Laser (Stairville DJ Lase 150-R ). The cable is long enough and of okay quality. HOWEVER the button itself (all parts, even the silver bit), is actually made of thin, cheap, shallow plastic that feels utterly fragile, especially if pressed strongly in a emergency situation. I am not surprised other users report early faults. It does its job, but I was definitely expecting something decent for 30 euros, disappointed.
