Most people will not believe a review website ! Why, simple because there are to many fake reviews on those websites. What you can do is making a REAL REVIEW BLOG or VLOG with your own reviews. And I am sure that there are already some out there. But the idea would be that you actual will talk about items you use yourself. (And that is more then you think on yearly base)
So, it can be a general blog or vlog about whatever you buy. Or it can be a specific one, like for example all the electronic you buy !
Again, just a free idea to get you starting ! Let me know if you set something up and I will mention your website here in the follow up of this (Short) article.
