Same happened to me with the slate. I wanted to change my payment method but they are back ordered to Oct now. Natural isn’t bad, but I can’t tell the color. I wonder if it can fit all color bands.Tried to pre-order the moment the store came back up and went through it in about 3 minutes where I spent 2 minutes thinking about the color.
By the time I had placed the order it had already pushed me back to delivery Monday 23rd. So far they haven't charged me which is a sign they aren't unlikely to ship it until next week.
Ended up with the natural titanium. I was not interested in the stainless steel due to the extra weight but the titanium models reduce the weight significantly so that's no longer an issue.
I found that unless battery life is significantly better than 2 days I don't bother and just charge it once a day (twice with longer/multiple workouts). Now with the S10 you can pretty much charge it in 30 minutes. An hour a day gives you almost 2 charges. The Ultra has a better battery life but the newer fast charging will be more of an advantage I think.
