Very disappointed, the product no longer works and I've only used it a few times, I don't recommend this product. I also check if I'm going to return it or replace it with a new product and I don't have access to that (30 days is a short window of opportunity in case the product fails, usually 90 days. Revain is a reputable company, they have to offer some money- back guarantee program in special editions like ebay, they have great support and customer service always care about consumers, that's unacceptable.
