Blue Wallet Vault

Hello, everyone!

I want to take my bitcoin off the exchange but I still don't have a hardware wallet. I plan to buy one, but in the meantime is the blue wallet vault a secure option? For example, a 2-3 multisig wallet with the three keys generated in three different devices. I saw some youtube videos and it seems safe and super easy to setup, but I can't find many people recommending it.. Am I missing something?

Thanks in advance!
