I researched this product through review videos per youtube. Just type in product name and model.
The product arrived by overnight delivery, as expected of Mightyape's superlative service. I did a quick brew test, unfortunately I had only a fine ground coffee and this was not ideal (as warned) and I had to stop halfway through the extraction, due to trying to push water through the dense grounds, as warned. However, I was able to retrieve enough brewed coffee to do a decent taste test. Wow, pleasantly surprised to find that despite my botchup I had a very nice tasting coffee. No sediment taste at all.
My advice: first, READ THE MANUAL, VIEW THE VIDEOS! Do not seperate the brewtube from the thermo cup unless you have the cup on a firm surface and well braced. Watch out for drips of hot water.
