I purchased the BB-1700 series two weeks ago. So far so good up until now. It's another level of experience I've ever had. They sent the product with care and provided fast shipping. BB-1700 was so smart, it has a stainless steel nozzle to be easily cleaned and maintained. You know, the BB is manufactured in South Korea and I know that South Korean people typically use the bidet for a smart and clean bathroom life. So I was very excited to have it and it's perfect for me and my family. I'll recommend it to my friends!
