Well to my own opinion, you can buy their product if you have the cash but I will be basing my decision on the following:
Durability: Huawei products are very durable, meaning they will last longer and it will not easily develop faults, even the battery is quite strong although not as strong as Nokia 3310, if you have used such a phone, you will understand what I mean, but strong enough for a smartphone battery.
Dual Sim: This particular phone is dual sim, which makes it more economical for you since it will reduce the number of phones you will have to buy or even carry around.
Portability: from the pictures you uploaded, the phone is quite slim and very portable for you to move around.
These are the few things I know about Huawei honor 7S, I hope we can get someone with a better knowledge to help us out the more.
