So unpacked, read instructions, cleaned as recommended and then from the freezer. Waited three hours, mugs rausgeholt and losgelegt ---> unfortunately a huge disappointment, because it has not worked out first.
Then again, does not work in the freezer for longer hours, again brought out ---> again.
Since the first disappointment was great. Well try again. Cups in the freezer overnight and behold the next day it worked. Wonderfully delicious Coke slush and then again the same evening a Bananensaftslush.
So what was it that it worked the next day, do you? So you have to really make sure that the cool packs in the cups are really frozen. You really have to be hard, otherwise it does not work.
I have for the cooling superscript from refrigerator and depending on the performance of the refrigerator may provide for more than the last 3 hours until the cool packs are really frozen.
When one considers all this and waiting long enough, it works just fine. As I said previously tested with juice and cola. Later or tomorrow is still syrup water off. If that works, you have a huge variety of flavors that you can to try each.
The cup is also very easy to clean!
So my conclusion: one must first try around rauszubekommen something about the pivot, but if you know what to look for, it is really easy and works really well. Delicious, it is also, and I am so excited with what drinks there any other works).
So strong buy recommendation, even for the slightly high price. For me sichs hats worthwhile.
