EZ-Cup Filters by Perfect Pod - 1 Pack (50 Filters)

I came upon the EZ-cup product while looking for a replacement mesh filter that came with my purchase of a Keurig machine a year-and-a-half ago. I brew 2 to 4 cups day and have never had a problem with the Keurig. I prefer coffee strong and black and devoid of grounds - and that is what I have consistently received using the Keurig brew-your-own adapter. As we speak, I am enjoying a perfectly brewed cup of Starbucks Vanilla roast. I cannot tell the difference between what I am drinking and what I have purchased from Starbucks or Barnes and Noble. Unfortunately, I saw a link to EZ-Cup and decided to read the reviews. Upon reading the reviews, there appear to be two camps: those who love the product and find it superior to the original Keruig adapter and those who find it an abomination. I am definitely in the latter group. Even many of those who liked EZ-cup discussed the machinations they had to go through to make it work "properly." I said to myself that it can't be this difficult. I decided to order the EZ-cup after several reviewers claimed that the resulting brew was much stronger than the Keurig, even though I estimated that using EZ-cup would add perhaps 15 cents to the cost of each cup. I received the cups and holder a couple of days ago, read the minimalist instuctions on the box, and had at it. The first attempt resulted in what can only be described as slightly colored, tasteless water. Ditto on the second attempt. I remember reading in the reviews about the placement of the spring, the best grind to use, the proper way to seal the lid and placement of the paper filter, and how high to fill the EZ-cup with coffee for optimal performance. My conclusion: since I followed all the instructions on the box to the letter, there is no way I'm going to contact the vendor like so many others had to, to make this product "work." I did not go to their website - I sure hope there is a video demonstration there on how to do what should exceedingly simple.
