1. I regret not following the advice of previoUs reviews and avoiding this dishonest seller. Mark provided a fake tracking number and never shipped the tube. When I reached out to inquire about the delay, she replied, It will be shipped tomorrow at 8am, which turned out to be a lie. No apology and explanation was given for not shipping. After several weeks of waiting, I had to open a case with to get a refund, which the seller did not provide. Eventually, had to intervene and refund me. 02-15-24
