Blockstream jade plus

Went with a Blockstream jade plus as my first hardware wallet. For those that own it how do you guys like it?

Also I’m still trying to understand a watch only wallet. If all I’m doing right now is holding, sending btc from strike to cold storage is it safe to use the Blockstream green app or how would I safely view my balance?

Still new so trying to understand everything.

Any advice is appreciated.
