**UPDATE: DELIVERIES IN JANUARY. EXTERNAL REVIEWS. SUPPORT RESOURCES. BATTERY LIFE UPDATE** Our production has been on schedule but unfortunately our packaging supplier in Kiev was affected by the power outages from the constant Russian shelling of the Ukrainian infrastructure. As a result, our expected shipping before Christmas was moved to January. I am very happy to announce that we have just received the first batch of final products and will start shipping to a significant number of pre-order customers in the beginning of January when the Christmas frenzy is over. The web shop will change from pre-order to in-stock during January. **External reviews** We have had a number of pre-production units delivered to 15 external testers during November and December, and their feedback has been valuable in creating the final release versions of firmware and the smpl Homey app: firmware v1.18, app v2.1.16. You can already experience several reviews here.

This does not include re-connecting and frequent use of the back button and thus full screen refresh. On the other hand, this also does not include using the pause/resume flow cards for power saving as well as reducing the update frequency, which will have a significant positive impact. --- _[View the full topic](https://community.homey.app/t/smpl-mini-display-battery-powered-e-ink-display-made-for-homey/55191)._
