Review on Lens by Patrick Matin

The lens is very useful because it offers so many scientific topics that are helpful for students who want more in depth information about their studies than they can find online or at school library, especially those studying health sciences which I am currently working with! It also allows me access anytime from anywhere if i need help finding something quickly like when you have an assignment due soon!! Sometimes there could be some lag time once uploading documents but this doesn't last long unless your computer has low RAM memory (RAM).
