What do you like best?
Dropbox Plus offers a good amount of storage for a reasonable cost. (It can get pricey though if you need a lot of storage.) It's easy to sync with your computer, and access things via their website. The best feature of syncing with your laptop is the selective-sync, which lets you choose which folders you actually need at the moment. It's a great way to keep backups of files, or just store projects that I'm not currently working on.
What do you dislike?
It can take a very long time to sync files sometimes. Many times I have to leave it syncing overnight, even though I have very hi-speed internet connections.
Recommendations to others considering the product
I would recommend Dropbox Plus for anyone looking to save backups long-term, and for selective-syncing files to your computer.
What business problems are you solving with the product? What benefits have you realized?
I have a small hard drive on my laptop, so using Dropbox Plus allows me to easily store files that I'm not using on a daily basis. It's easy to choose which items I want synced to my laptop, or just stored in the cloud. It's also great for sharing with coworkers and commenting on documents. I'm able to share a draft of things I'm working on and have multiple coworkers comment on various parts of the project so everyone can see everyone else's opinions. I find this part to be a huge benefit over Google Drive. It's far easier to use.
