As I have wrote before about really interesting dual-sim smartphones called Doogee DG750 and Mlais M52 Red Note. In my opinion they are both interesting because they are selling at very low price offering at the same time strong hardware.
So for example Doogee DG750 has MTK6592M Octa Core CPU with speed 1.4 GHz and it has 1 GB of RAM. It has also 8 GB of internal memory. It is a smaller models and because of that it has 4.7 inch qHD IPS OGS screen. According to the company it has 2000mAh battery. The regular price is $99.99 and you can buy here at 1949deal.
When it comes to Mlais M52 Red Note you can see that this smartphone has much more stronger hardware. So it has MTK6752 64Bit Octa Core at speed 1.7 GHz and in this combination it has 2GB of RAM. It has 5.5 inch HD IPS OGS screen, so you can see it has much bigger screen then Doogee. It also supports 4G network and has battery with higher capacity in this case 3200mAh.
For Mlais M52 regular price is $147.59. And for this purpose I have prepared coupon code: 1949deal0808 which lowers the price for $3. Using coupon code you can buy this smart phone at this Chinese online shop called 1949deal.
