Query: Very pricey for the quality

I purchased this product, ignoring some of the negative reviews on the difficulty of use, etc., assuming that as a well-educated person, I could use it. Hey, I even roast my own coffee beans. I have had the Mukka Express for three years and drag it out periodically, determined to master it. Inevitably I have milk and/or coffee everywhere. I have tried lower heat, higher heat, fastidious cleaning of the gaskets, etc. Nothing works. Save your money. For what you pay for this little pot, it will buy A LOT of coffee from Starbucks!
