I love how everyone can be in the same chat room. You can add people, so there are no strangers in the system, which makes it easier to get used to. The customer help and support is great also, they even have training videos for new members. There isn't much for me to find wrong with Hollo as the only thing I could think of was that sometimes when you're typing, your text comes up twice. Just remember to get the hang of using the chat function and you'll be fine! If you want to connect with your team members at home and work without being interrupted by phone calls or texts. I love how it is easy to use, no matter what device you are using (mobile or desktop). The only thing that can be improved would probably have more options for customization of your profile picture as well as photo filters in general! This has been such great help with communication between my team members from different locations around our country/world at times when we don't all get together often enough!!
