Gaea and others wrote in their review that it is difficult to dose the glue - I can also confirm - I do not get well after multiple adhesive Try to apply as little glue that did not happen afterwards herausgequollen when pressed, thus resulting some problems with the positioning of the pieces.
In my opinion, good (of strength) bonding results can be reached - the broken handle of Kaffeepötte have kept even after transitional dishwasher. Whether the look appeals after gluing each, to each his own discretion (see pictures above) - maybe I was just a little awkward, but I call myself just once as laymen, and that's probably almost everyone who tried something like this for the first time.
I lacked definitely the indication of whether you (etc. dishes, butter vessels) may still without damage to food from bonded bowls (1 point deduction).
The look I was also not necessarily convinced that almost all of my parts were not only broken, but also chipping at the breakline had that automatically fill with the light adhesive, and then you just white glue in dark porcelain.
So I see myself not optimal result and awarded 3 stars - but for example to save a favorite cup in my opinion is the price-performance ratio attached to a trial.
For fine and especially valuable porcelain should be noted that there are porcelain doctors reattach eg Henkel on cups and the cup slide again into the kiln - as you can see then probably no difference to a new cup more.
Addendum of 30/01/2014
========================
Now, my two cups in which Henkel has been glued back but unfortunately wandered into the garbage. Sparked on both cups after 4 months of use and about 1 wash per week (still have more cups ;-) in the last days of Henkel in the dishwasher off again - I'm glad I did not exactly in a full cup of coffee hand held, but this happened in the dishwasher. Perhaps this would not have happened at hand rinse with omission of the handle, but who does that? will also be promoting the manufacturer precisely with the durability even when using hot water and Spülprodukten - this applies but obviously only for a limited period.
For everyday use, this product is not recommended for me, anyway - still just for "visual repairs" for people like me bad eyes or things that are only used as decoration. And that remains for me only 1 star for decorative purposes. But I had a terrible buy the glue!
