The least of the product:
- It only works if it is plugged in. This involves being on all fours to set. It's not very convenient, especially for measuring consumer products recessed TV type.
- The batteries insert into the device are useless: when the device is disconnected, it no longer works and loses his memory (last measure, KWh tariff settings). It's a bit boring. (Putting the batteries did not change the operation)
- Manual unusable. Not in French, and I'm speaking German and English, I did not understand the explanations provided!
Overall I am satisfied with the product that meets my need. I use it to estimate the consumption of the most energy devices over a long period, to extrapolate the depreciation schedule of a possible replacement of energy equipment.
I hope I have helped to get an opinion on this product.
Sincerely,
Thomas
