Don't do business with this company!
Order device. Tried to cancel order two hours later. Was told that the warehouse had already processed order. They up sell you on other offers. Which I click no thanks. I never finalized order. Was charge for extra items. Two weeks later still haven't received items. This company is a joke/ fraud. Should be reported to consumer agency!

It's a scam
It's a scam, doesn't do anything. People are gullible, if it worked, then car manufacturers would fit this, based on the fact that car manufacturers try to get the best mpg from their cars, as fuel economy is a major selling point. It's just a plastic box with a light on it. No I didn't buy one, because I'm not stupid.

The Company made immediate plans to investigate and resolve one of two problems that I I hard with an order to be shipped from them. They noted to me that one of their employees would investigate the situation and get back to me with the results, so far it is to soon to expect the investigation. So so good.
