Long ago I seek a steamer without bisphenol. Well I found a wonderful one and recommends it. As steam as say some reviews, I noticed that evaporation was normal and sufficient that the area is well ventilated. The timer while cooking is not a small ticking noise but bearable stops only. It is especially important to let the device end its cycle. That little negative things to say not at all for me. Shipping with Amazon and perfect delivery as scheduled. Thank you. REYMOND
