Bests & Worsts Reviews from Amazon

purchased and Installed the unit in bath room after adding an outlet. after that, we immediately found that the unit causes bath room light flicking. after a quick google search, we found that some customers experienced similar problem as well. Because we can't use the Bidet toilet seat on the same wire with bath room light. A dedicated wire is required. for sure, this information was not mentioned in the product user manual at all. Thus had to spend extra expenses to get the 2nd outlet installed. doubled the work and cost. Bidet claimed to ensure customer happy. Thus we contacted them. while their response shows more concerns. Here is the quote from their customer hot line "this product is for use on a nominal 120V circuit. In other words, a dedicated circuit. When a unit is not installed on a dedicated circuit, you can experience flickering lights when attempting to use the product". this statement might be able to drive away customers without engineering background; however not an experienced hardware engineer. According to Wiki, in the US, the nominal voltage is 120 V, with variance allowed from 114 V to 126 V (±5%). it doesn't mean a dedicated outlet. I suspect it is a design issue due to without sufficient noise blocker for the AC line. obviously Bidet knows the issue but didn't fix it or noted in the installation guide. Bidet should be responsible for the extra efforts customers put due to their design; certainly they didn't make the promise to keep customer 100% satisfaction. certainly not that easy for DIY. Thanks for reading it! Hope it helps other buyers save some time.
