Initially, I had a problem with my first bead, mal-function and packaging. In fact, I was really dissatisfied and do not fail to know through my notes. The company Kalea who is responsible for shipment to simply react in the day, and indeed, with such professionalism that I have to point out. In fact, they did not even wait until I return them my cord to send me another one. Failures there always and in every business, in reality I think the real value of a company is not simply to 5 stars when things are good, but more is to manage precisely the glitch; and there is really no fault to them more difficult to consider the customer and be more effective.
