I have been waiting a month for my $91.00 of product... was guaranteed "fast shipping" 4-7 business days... ordered Dec 3,2019... has not been shipped Dec. 18,2019... they respond to emails with sorry waiting to be shipped.../obviously coming from Asia due to tracking info... but will not grant refund... as everyone else says... should of read reviews... advertisement looks so good! And is "trending", but a scam I guess.
