I have seen multiple bidet options at different places at varying price ranges. However I must say that this gives the best bang for the buck. There are a couple of key factors which I would allude to for this product:
1) A great bidet at it's price range. I got it in the indiegogo campaign and it was even better in terms of price (but hey crowndfunding backers need some benefits right ;) ).
2) Super easy installation.
3) Extreme focus on quality - There are multiple other bidets at this price range but the quality is sub par. biobidet instead focusses on quality such as using metallic joints, good quality plastic etc.
