I've been using it for a while, it's very good if you are using altcoins in addition to BTC, not sure about the security details but as far as I understand it require some trust in an intermediate party (without access to your private keys of course) in a similar way to Electrum.
I am using both electrum and exodus in 2 different computers from quite some time now and both are quality wallets. Trusting them is an issue but their service is good with Bitcoins as well as altcoins.
