As many of you know, we are the FIRST to pioneer the Magsafe DC car/Airline solution. We continue to offer the best options and prices for our users. However since we have started this conversion a number of competitors are copying us, and in particular one competitor MAY be bad mouthing our products to our potential customers. We normally do not like to enter into this arena of debate, but it does deserve mention. We’ll just say this, our customers from day one have been 100% happy with our solutions, 100% compatible with ALL Macbook line of computers, and we would not still be in business if that was not the case. We guarantee it.
