From the principle of Ansmann AES3 ZeroWatt is awesome: The socket is learning how much electricity connected devices in standby consume and automatically de-energized after a minute, so that the standby power consumption to almost 0 (zero) watts is lowered. The cable for the switch to turn on is sufficiently long. Up to this point I would give it 5 stars!
Unfortunately, I have the same problem as many other reviewers here: The first unit has held a 3/4 year, the relay has not switched off. While the indicator light goes out and the relay switches audibly, but unfortunately still is the full power of the connected equipment on. The standby lamp lights continuously. The seller (Mobile Ernergy) referred me directly Ansmann and will know why. The customer service from Ansmann has however responded exemplary. After sending in the AES3 I got problems within one week replacement. Now, after a further 3 months, this exchange unit is defective with the same error. Quick mail to Ansmann and I got this time even a replacement unit without return of the defective. So I suppose the problem even when Ansmann likely to be well known. Let's see how long it keeps this time.
Conclusion: The AES3 follows a great idea that was implemented unfortunately too cheap (Made in China). Thus, it is designed for continuous use, unfortunately impractical. The customer service from Ansmann is indeed exemplary, but here yes the device is to be evaluated. That is why only one star. Ansmann are on the AES3 Although three-year warranty, so still a lot of electronic waste is ultimately produced. I can only advise any interested party of the AES3. And if the AES3 should be bought and defective already been, then it should be made of the three-year warranty use. Perhaps the leaves Ansmann AES3 then produce something durable. Worth it had this great idea in itself in any case!
[Update: It's striking how many of the negative reviews were here "unhelpful" punished with Amazon in a very short time. Evil to him who thinks evil. Either or want some defects as often described here not imagine or a highly efficient multimedia Argentur was commissioned. Who can view the most helpful reviews currently taking (18.03.2013) on the first 6 pages ONLY A negative review. At total of at least nearly 25% (23.4) and two star reviews I think that's quite remarkable!]
