There was an average Odyssey to the SocBlue was with me, because the seller has responded exemplary and helped. For product: It does what it should and the good, but for me the start worked out only with the help of the seller. The unit appeared in Bluetooth just not on. Finally, must be pointed out that the PIN request of the inserted SIMs deactivated - which I find problematic, however, for security reasons. Unfortunately lacks any reference in the documentation for this request. Of course I had the SIM card to expand again and thereby showed that the wells are not designed for frequent changes. The Bays go virtually it at the first exchange, spare parts, there is not for now. However, this is more of a visual problem, the function is not affected. Difficult are in my eyes 2 things: The app, there are no by-Play Store, so you need to turn off the corresponding security feature to install and update, which I personally do not like to do. But maybe that will change. The app is great, but only available in English (about Chinese help you just have wegblättern when you first start, 5 pages, then comes the English). The other: As long as the app is connected to the SocBlue, Bluetooth is on, both app & Bluetooth massively attracts, battery (as evidenced by the Task Manager alone the app to 18%), after 10-12 hours with my Galaxy S2 battery at the end. One should therefore app in Task Manager by hand stop when it is not needed, otherwise it moves on in the background. Main criticisms in the flyover: # High power consumption # Incomplete documentation # Fragile construction of the SIM slots Function does the thing as promised and properly. Supplement: The latest version of the app is much more gentle to the battery, the power consumption is geschrumpelt to something between 30 and 50%. Only weiterso.
