Was expecting product to have the coiled cable shown in the picture, but it didn't take much to coil it myself. For the price it does what is expected. I have used it without placing it on the cable system yet just to test it. Using an LED light bulb, so it does not really test the integrity of the fixture since the power draw is not significant enough to heat the terminations. The bulb holder end requires you to tighten it with a technician's screw driver to retain the bulb. Make sure all terminations are tight though if you use a standard halogen type bulb. If the terminations are not tight, this product will heat up and burn out, but that is typical for low voltage lighting.
