Box is a good software, I like things about it which are:
1. Box can work very fast on android phones as it works fast on desktop too. So you can access your account from anywhere.
2. Box gives a very large space of 10gb to store files, you can literally store anything from your images, videos, pdf's and you'll still have space left.
3. Box is relatively cheap. Since we have started using box in my company, we haven't paid anything.
4. Uploading speed on box is good too. It mostly doesn't lag when ur uploading
5. You can aslo have numerous accounts easily on box, for instance, we just opened a new account as shown in our screenshot below. So an additional 10gb left to fill!
The only glitch I have noticed about box is that sometimes the files you upload on your phone doesn't appear on your desktop version immediately, this has made us waste time in accessing an important document a certain time.
I just love box for it's large space, I recommend it 100% to anyone, it'll really come in handy.
Box has helped us organize our files well without fear of loss of documents or anything.
It also has helped me personally to carry less documents around because I know that once a desktop or phone is around, I can access my documents.
