Good deal, just didn't like the pushing of other items I don't want. Other than that good experience.

This website fraudulently adds…

This website fraudulently adds additional items to the order that are not authorized. From what I read, the device results are less than advertised. I would NOT RECOMMEND purchasing anything from this company and I will file a report with the Attorney General’s office for their fraudulent activity.

A quick response from the support team

The support team was quick to respond and search a satisfying solution. I finally got a full refund for my order. However, all this experience would have been even better if from the beginning I would have been able to revise my order and discard the products I was not really interested in. In this way I would have already purchased the only star product I was really looking for.
