nRate

I used to buy ratifyapp.com and ahreview.com, ratestar.io but later I was able to purchase https://nrate.com at a very good price.

Then I bought a WordPress directory plugin to try on my new domain since Joomla is declining... The plugin is Directoris and has very limited features.

I Googled for a good CMS and ended up with Joomla (tried WordPress but the UX is terrible IMO). I picked the JReviews extension for my site and started building it (I don't know to code).
After few months and many support emails back and forth, I have the first version of my review site!

I couldn't find a review for a cooker I plan to purchase although I search everywhere on the local and global search page. Then I came up with a review site that has the reviews for everything.
I quickly searched for a Vietnamese domain and found a good domain for sale (danhgia.net) which mean "review".
