Excellent coffee, have enjoyed it for close to 2 years. Over time, the mesh filter started to clog. It is very fragile so there is no way to clean it thoroughly without breaking it. Hesitate to use harsh chemicals. Yesterday, it started to leak. Tried to disassemble the unit but then noticed that the plastic screw became misshapen,  probably from cleaning the unit with pretty warm water, and I could not remove it. To my amazement I learned that the unit has only one-year warranty, so I am out of luck.  Debating whether to buy a new one. Probably not. Too bad because the coffee, provided that you use good quality beans is superb.
