I was initially skeptical about whether a phone from China can any good, before I had only bought smartphones from established brands, but was not willing to continue to spend so much money. My requirements (no more than 250, - EUR / lots of storage / good performance) would have in a brand device (eg Galaxy S4.) But with approximately 400, - to beat Beech EUR. I then found this device and another Chinese cell phone (Zopo 988), both with good reviews and tests both on Amazon and elsewhere on the net. Since the Zopo had only 1GB of memory, I have decided for the thl T100s. And - it's all true. The device is really fast, there is a floor Android 4.2.2 installed (German), so no annoying bloatware apps or Chinese characters. After inserting the SIM card, and pairing with my wireless, I could losarbeiten immediately. The device will boot fast ( The only weak point in China-equipment: In case of warranty, there could be problems in the implementation. But the risk I take at a price saving of around 150 EUR, compared to a "brand unit" gladly accept, especially since established manufacturers often provide only 6 months warranty (Tip: Buy it at German dealer / importer, is only slightly more expensive but has a contact person).
