I bought the 10 quad IEOs 4 Tablet from Amazon as a Christmas present for my wife. According to article description, the device has a quad-core processor with 4 * 1.6GHz and 1GB DDR III RAM.
When you set up your tablet for these facilities seemed to me plenty of lazy. In ES Task Manager then a free space of 100 MB is also a maximum display. In a Youtube-review I saw here a value of more than 500 MB. In the APP management (running apps) I realized then that the tablet has apparently not given 1 GB, but only 512MB of RAM, which was also confirmed by an appropriate test tool. Although this tool will detect the processor with a clock frequency of 1.6 GHz declared, but indicates that this frequency can not be reached on this tablet. Instead maximum 1.4Ghz been achieved, what would have been still acceptable with 1GB of RAM.
CONCLUSION: If there is what is on it, then that is certainly a Tablet with a top price-performance ratio. If, however, is only half of the specified RAM available, then that's just an absolute knock-out criterion. So returning inevitably and unfortunately only 1 star.
Probably I was just unlucky. Still, I had to replace another well-rated and tested tablet with similar specs, ordered at a comparable price. Burnt child dreads the fire after all. Should I also have problems, then I put just one more thing on it and see myself around in expensive competition.
