The overall quality is quite ok, however feel that the processing of the rough edges of the seat are a bit "cheap". There is also a star deduction considering the price.
The self-closing function of the toilet seat, I felt initially rather disturbing. Meanwhile, I was convinced this technique and I must always be careful with strange toilets, not to let the seat fall, how is it possible for this product.
I can advise everyone to this seat inspected visually for such a variant. The choice is very limited and wrong does it do nothing. Conclusion: 4 stars.
