HI Everyone, went to Hoe Kee recently to look for instant heaters. Stumbled onto this Rubine Model and was told that it is fairly new. http://www.rubine.it/products/proddetail.aspx?ID=380&CateID=71 Anyone have any thoughts of this? in terms of water pressure, etc. I live on the 2nd floor, so my current handheld shower and taps have good pressure. Thank you!
