I have been using Mouth shut from 6 months and here is my review on it.
Service and support: Service and support is not good as whenever I face any problem I either mail it or send it in the message but I didnt get any reply till now. I have several questions to ask but I am not able to ask because there comes no reply from there side.
Information depth: Information depth is also not sufficient as whenever I check any product to write any review on it I didnt get any kind of important information on it.
Content: The content of it is very good as this app makes you earn money by just writing reviews or sharing your personal experience on it.
User friendly: This site is good and user friendly too as its structure is simple anybody can understand its content very easily.
Time to load: Sometimes it creates trouble while loading and information about any product otherwise it is good.
I will recommend this site only to those who has patience.
