According to "TuneUp Utilities 2013" (Program Deactivator) slows down the software from my PC by about 25%. I barely have a program consumes nearly as many resources in use. (Not even my antivirus program "G Data IS2014" burdened my 32bit Windows7ultimate PC so strong.) My Windows Experience Index is 7.4. Therefore, I can probably cope with this burden. I know, however, not whether this is normal? A final vote I can therefore not give, but nice, I think not! The software had to be installed twice, because they did not work after the initial installation. The Bluetooth USB flash drive is now working reasonably stable. I stream music to a Bluetooth 4.0 so speakers. The is currently only about two to three meters. Nevertheless, occasional jitter heard. The range appears probably not get very far without errors to work. The product is as mentioned only moderately. I could but unfortunately not find better, because apparently all Bluetooth dongle ehr are inferior ... I'll light of this experience rather do without Bluetooth and work again with conventional cables.
