So this is going to be a slightly different review because i am not using this product as a bottle warmer, however I expect it would perform that function extremely well. I need to wear a dental appliance made of thermoplastic to control my Sleep Apnea. This means that before you wear it, you need to get warm it up so that it becomes soft. Too little heat and its still hard, too much heat and its too hot.
The beauty of this device is that you simply set a temperature, and it then maintains the water at that temperature until you turn it off. Most other baby warmers you will see do not have this level of control, and simply keep heating up until they turn off. Really very simple but exactly what you want, and it can stay on for hours. It starts in the 30 degree range, and you can raise it in 1 degree increments until 40 degrees, and from that point on in 5 degree increments up to about 85 degrees i think.
Not much more to say, does exactly what it says on the tin, and does it very well. For anyone else in my position this is a godsend, however for people wanting to use it as it was intended i expect it would also be a wonderful labour saving tool.
Only negative, its quite light, and the buttons need some pressure, so you really need to have two hands to turn it on and off, 1 hand to support it, and the second to press the buttons, but this is a minor niggle really.
