Welcome to our tech site. Glad to know you write reviews. We sometimes conduct contests on comparison of products which thereby involves reviewing these products' features, their pros & cons. Do look out for such contest announcements in our forum. Look out, too, for queries in our Ask Expert section where we have members & visitors asking about which product to buy (a smartphone, a bike, etc) or asking whether a product's features are really unique enough to make it worthy of a purchase.
Once you establish yourself as a serious contributor to our site with quality posts, you may get permission to submit products and their details in our products review section.
If you need any guidance and have any queries, however small, do post them in our forum & we will help you out. Hoping to see some great contributions from you soon.
