Performance: Feels very sluggish - was expecting somewhat similar performance to my older 2015 Fire 7 but this actually felt slower on the same latest version firmware. May improve in future updates but this is a major uncertainty.
Battery: Drains to 0% in 4 days standby, 2 days passive use (15 minutes every few hours), or 4-5 hours active use.
Weight: Very light, it feels lighter than my old 2015 Fire.
Value: At $40, this is a decent value as long as you manage expectations. I received 25% off for trading in my old tablet and including the trade in value, my total cost came out to $30. There was also an additional $10 appstore credit promised for pre ordering but I have yet to see this reflected in my account. This tablet is best when not utilizing any data-heavy or graphic-heavy applications as it will be a major slowdown.
Great as a on-the-go video player, ebook reader, and general tablet for trips where you wouldn't want to lose your primary tablet.
