Had mine for over and year and I love it!
Only problem is that the powder gets stuck all the time and never dissolves properly..
I follow the directions exactly. Water NEVER above the line and sometimes even use less than the 1/2 tsp of macha powder.
The only problem I am facing now is that the pressure button came apart from the rest of the lid this morning.. :(
I can still use it though. I am waiting to hear back from David’s Tea regarding this issue…
