I love this distiller! I've had it for over a month now - using it almost daily. It's very easy to use. Mounting the handle on the glass carafe was bit of a challenge, so be patient. There is some limescale, but that is somewhat expected, and it is really not that bad. I repeatedly tested the water before and after with a digital water tester (from a completely different vendor) and it consistently tested within 0 - 50 (TDS in parts per million) after distilling. Would definitely recommend this product!
