Got the DT-903 bought (1520 930) as a charging station for my Lumias. The quality is Microsoft / Nokia typically at very high levels. The DT-903 is in full and by the rubber coating on the underside verutsch this not as easy as in other cheap QI charging stations partially the case. The feel is very valuable, it knarz nothing and the gaps are also top. From the optics, the color fits perfectly with my oranges Lumia 930 and the integrated lighting makes the DT-903 a real eye catcher on every desk. The coupling via NFC worked right away and you end up right in the hub devices. There are several Einstellmöglichkleiten for lighting intensity (high, medium, low or off), notification to the battery level (the station 'glows' when coupled with the smart phone and the battery level is below 30% decreases) if one comes in Bluetooth range. You can activate the visual notification for up to five apps unit flashes 2 times quickly when a new e-mail, SMS, etc. has come. For those who wish to use the charger in the bedroom should be said that there is an adjustable night mode (start time and end time to enter, ready) disables the lighting. Loading my Lumia 930 has the DT-903 lasted only unswesentlich longer as with a cable. Here I have to say that I do not operate the Station to a USB port but the use the Lumia 930 with supplied AC60E charger. On a USB port of loading Vorgangn is probably due to lower supplies current to a USB port might be slightly lengthen. The loading and the additional features I tested only with Microsoft Lumia smartphones. I can not say whether the additional features also work with smartphones from other manufacturers.
Conclusion: A thoroughly enjoyable product with high Quälität and ingenious useful additional features. Anyone looking for a really good QI charging station which also optically what the fancier is right at the DT-903. From me there is an absolute buy recommendation!
