So I have been asked to review this item...which hasn't even been shipped! I ordered it 3 weeks ago and apparently it should have already been here! So not sure how I am supposed to review it! But I will review botach, first order was shipped fast and arrived in a very timely manner and was a great purchase and purchase experience but...this time I can't say it's been the same! Poor communication poor shipping time (or lack there of) and have been asked to review a product they haven't even sent me!
