Despite the not so good review existing I bought the Unbelievabowl and was not disappointed! As it is written in the article description keeps the suction cup only on very smooth surfaces, which indeed is totally logical and if you still buy the bowl, although you do not have very smooth table, you need not complain in my opinion, if the suction cup does not hold , However, we have a high-gloss table and Unbelievabowl holds so rock solid that it theoretically could thus lift the table! The baby bowl holds so what it promises. Conveniently, you can buy more shells without suction cup, the one needs finally only once. Then the price per dish is not quite as steep. All in all, a strong buy recommendation from me! If you have a high-gloss or glass table, if not, stay away, because then holds no sucker, neither this nor any other!
