Based on a number of frustrating experiences with Sanicare.com (in particular the owner, Robert) I strongly recommend not doing business with this company. Robert initially discouraged me from buying the product I called in to purchase, gave me misleading information on product comparisons, and then when I attempted to return the product for the one I had originally called to purchase, he was not only incredibly rude, insulting and disagreeable, but refused to accept the product back in return for the one I wanted, and then refused to respond to my phone calls and written requests for various remedies. I have rarely been treated so poorly as a customer, and his complete refusal to accept any one of a number of my suggestions to meet me part way speaks to his lack of customer support. He quoted his web page that such personal items were not returnable, yet he never told me during our discussion that if I did not like it, he would not accept it back. Had I known this, I would certainly NOT have taken a chance on another product when I was so happy with the one I have been using. Basic details include: I originally called to order another of the exact Toto Bidet (SW553 I have owned for about 3 years, because it has worked so well for both my wife and I. and we were prepared to install one in our second bathroom. Robert proceeded to tell me that Toto is standing on its (old) reputation and has become technically obsolete, not keeping up with more advanced bidets (specifically the Coway BA13 he was steering me toward). Not being conversant on "bidet-talk," it was impossible for me to sort out his truths from his exaggerations, but I felt he would be the logical person to know the differences at some depth. I also knew there was no pricing difference between the two units, so I had no reason to suspect he was just trying to extract more money from my purchase (although now I feel it is possible he either had a falling out with Toto, or gets more commission by selling Coway). The bottom line is that I purchased the Coway on his strong and convincing, indeed compelling statements about the superiority of the unit over the Toto. Immediately upon installation, and every day since then, both my wife and I have been disappointed in virtually all operating aspects of the Coway. I could provide details on a point-by-point basis, but this is already too long a message. The real reason for writing this is not to attempt to "sell" people on my preferred Toto unit, or to badmouth Coway. It is to try to persuade buyers to use a vendor who is more customer-oriented and less antagonistic. There are so many to pick from…why use someone who won't even return calls to work out a mutually agreeable solution?
