The operation is very simple: Desired ingredients in the blender jar filled (600 ml mark not exceed) - blade attachment screw bottle so press on the motor unit or with a small rotary movement for prolonged mixing snap after mixing (no longer than 30 seconds at a time!) the blade attachment to the drinking cap exchange - done.
The bottle is properly sealed, with me nothing works out. When drinking it is by their slight indentations on the bottle wall very well in hand. The drinking hole I find big enough for thicker smoothies (2.5 x 1.5 cm). Irritating is that sometimes collide with the nose against the top flap, or the small door to the nose drops. But that does not really bother me and is no reason for me for a star deduction.
The cleaning is very easy. Either the same after drinking all seek or give also bottle and essays in the dishwasher under running water. Or fast water and a little washing up liquid into the bottle and mix. ;)
Something strange appears the initially strange smell (like burning) the mix, but that was the time continuously decreasing so I suspect that it was the beginning of odors.
It's great, I find that the blender with frozen fruit, and even ice cubes has no problems and you can also make delicious semi-frozen drinks besides normal mixed drinks. Frozen berries and soy milk, milk, coconut milk or yoghurt is ready in the cup of semi-frozen smoothie. This is really fun. Also it creates cubes, but they should not be pure, but mixed with some liquid (juice or syrup) to protect the blades. The result is somewhat irregular, ie there is very fine ice mixed with a few larger pieces of ice, but it just tastes really great refreshing, just for the summer.
