We check our Facebook three times on the way to work on our smartphones more powerful than your computer.
We check our Facebook three times on the way to work on our smartphones more powerful than your computer.
Is this sentence correct? It sounds much better if we remove the ourour before smartphonessmartphones but since:
We check our Facebook three times on the way to work on big smartphones more powerful than your computer.
We check our Facebook three times on the way to work on big smartphones more powerful than your computer.
Is correct why should the original be wrong?
If it is wrong, what is it about OURour that makes it wrong?
