Over time, I made a couple of purchases. Both fast, very fast. And out of 4 products in total, one had a problem: in the last shipment, one of the products came with the seal broken, the box had the edges broken too, clearly, to me, the signs of the fact that the box was opened before shipping. The outside package had no signs of mistreatment during shipment. I wrote Customer Service and they assured me that no one opened the box and that it's all good. Well, it's not. The sum of experiences with a seller is only valuable as the worse of them all. I don't know how often this happens, I'm not suggesting it is a habit here, but if it happens to you, that's probably it. It's not going to happen to me again.
