Absolutely unstable ... Too bad!

Had ordered to fit a wiper of Leifheit the bucket, with the part but am quite dissatisfied. Once the bucket is filled, it can no longer bear, is totally unstable. The Henkel dissolves completely on one side and thus naturally tilts all the water out. The only way to bring the bucket "without damage" by * s house is, it additional support with one hand under the bottom. Then has "woman" of course, no hand more for free wiper ... Unacceptable!
The size of the bucket is good, but the instability does everything to naught. Now Plag 'I hold back with my "normal" round mop buckets rum and the expensive part is in the corner. Pity!
