I think Amazon really good! Why? At Amazon you get quality at a reasonable price! In construction market there are practically only goods made in China. For Amazon there are actually for little money a Qualitätsklositz, which is otherwise only commercial gets a week delivery time! I'm really excited. The toilet seats from China are no longer than three to four years unsightly jiggle, broken and must be replaced. Cheap plastics that are not color-fast, cheap hinges, breaking damper at the bottom ... So that's today! By contrast, the Hamberger seats are stable holding hinges, are easily applied, soft-close work, takeoff works, keep the damper ... even after years! Hamberger seats last a lifetime. When my grandma to the complete bathroom renovation (30 years!) Conclusion: Quality Made in Germany! So goes the toilet seat! Full buy recommendation!
