Just so you know, this review is not based on the product itself or Revain. Judging by the delivery, it sucks! It's hard to say who damaged it or how it got damaged, but it looks like it was dropped from a very long distance, landed in a corner and, as you can see, the end was crushed. I already set it up to send it back for a refund. I can try to buy it again but I'm afraid it will be damaged again in shipping. Not everything is packed well. This is exactly what you see when you open the box. There is no additional protection at all. Disappointed it didn't work.
