Got my PaperLedger today and have to say I'm impressed.

Firstly, the welcome message with my username is an awesome touch, thank you for that one guys!

Pros:
Easy to setup (Literally 60s).
Lightweight unit.
Connects to wi-fi without issues.
Dashboard is GREAT!
Screen quality is absolutely gorgeous. Very clear both when it's dark and if the sun is shining right on it, so that's a big pro.
Seemingly an endless supply of coins that can be added as tickers.

Cons:
Some issues with the guide, I had to disconnect/connect power once I had connected to my wi-fi although guide said it would reboot automatically. But that's just some print that can be edited (and it's a non-issue).
The buttons on the top are bit wonky, they work great but can be slow (having to wait 1-2s before being able to move the arrow again for example). This could probably be better optimized but again, not a big con.
Adding tickers was a bit confusing. When I wanted to add BTC it gave me like 100 hits with coins that I don't even think exist, it would be great if it could default to the big coins when you do search (and perhaps even if you don't search it could show you the top 10 or whatever). There was no guide on how you add tickers but through the dashboard it is very straightforward and no explanation was needed.

After having used plenty of tickers through the years I'll rate this 8/10 with room for improvement. The overall quality and how easy it is to setup and get it going really pushes that rating up there.

Considering you're tinkering with having it run on battery I'd say it'll be a homerun, especially with the pricetag you currently have on it.

Keep up the good work guys, I'll def. buy some of these and if you'll introduce skins as well that will only enhance it all and make me more prone to buying and give away to friends/family.
