I've switched all my landscape lighting to LEDs and they're a great replacement for my old 25w incandescent bulbs. I bought 6 bulbs and when they arrived on Friday I plugged them in and one of them didn't work. That same evening I sent an email to the support address regarding this. On Saturday morning I received an email asking for my address and that they would replace the lightbulb. Today, Sunday, a package arrived with a new bulb PLUS as a replacement! Aside from the fact that the lamps are perfect, I'm so impressed with the company's responsiveness that I would happily give it 6 stars.
