I highly recommend https://t.co/SgxEoVfJrw. It has been extremely useful for sharing artifacts across my team and externally. Claimed https://t.co/VP4sk4gh7d and the team is already leveling up. https://t.co/tBLHbn4Hby

Finally got my @Heypocket and I'm already a big fan. Everything about it feels like an Apple product, from the packaging to the onboarding and UI. I also like that it doesn't try to be stealth like other devices. All colors are bright and metallic and it literally says "Pocket" https://t.co/KKYseOmzgO https://t.co/XYRZXMK1hQ
