Unfortunately there is in the tariff-setting a display of the monetary unit in the display, making it for me at first was not clear whether the KW / h - price must be entered in euro or cent. He is entered in euros.
Unfortunately, this information can not be held with full accuracy. My provider has eg a KW / h. - Price of 19.9 cents net = 22.7 cent gross. You can enter only 2 points accuracy (2 decimal places). So I give a 0,23 and get as result a diet Enver break appears slightly above the actual consumption.
On one of my two devices that I ordered the function keys is not optimal, which is manifested by the fact that it partly press rather firmly. Must so that what does, on the other hand the keys are bad or not "bounced" what manifests itself in that in one-time press a button a "double-pusher" is executed, so when setting the tariff during upshifting of digits for example be able to:. 1-2-3-5-7-8 -... . Since etc. If this setting is not so often makes (possibly only one) is my matter and I keep the device anyway.
An otherwise everything works as much as desired, which is the "menu" very clear, so you far here can speak of menu navigation. You can see the max. Capacity, the current capacity, the consumption in KW / h, the total accumulated costs, the projected cost per day, per month and display each year.
I use 2 devices, for an oil radiator (950 watts) and a heater (2000 watts). For this, the part is suitable.
Because of the low price I see across the little weaknesses and give 4 points. For the price nice device.
