Good power supply with many plugs

After I had previously ordered another, interressantes universal power supply, I had to realize that exactly the plug for my Acer S7 was not there .. A call to the company brought no solution, the plug was not available. So I sent back the power adapter and ordered me Hama device. It has even more different plugs but pack also not the plug for my ACEER S7 in. In the call to Hama, which is also expressly provided in the manual, I was connected with a very nice customer service staff, who offered me immediately, send two additional connectors. After 2 days I had the right plug for my notebook in hand. The plugs are all very well done, large and stable, with a nose so as not to confuse the polarity. The power supply works to my complete satisfaction and can be switched easily to the required voltage. I am very satisfied and would recommend this device to anyone.
