Nanoledger thoughts/advice

I'm looking at purchasing a nano ledger S. I have done reading about it and I guess I'm admittingly a little old school about things... So, is there anyone that could comment on it, how they like it, what they don't like, etc etc. Reviews and shit only go so far on site for me and even though Reddit can be a dark place.... I know that you all love keeping your money safe more than anything. Any advice, tips, links are more than welcome. Thanks in advance!!
