I've been enjoying my Leaf Urban for a few months, now. Overall, I'm very pleased with my purchase! There are a few things I would like her to do that she doesn't... yet... but I'm guessing such improvements are in the works. From reading previous early reviews, the company pays attention to customer feedback and has already added useful updates via the app.To be honest, I chose the Bellabeat Leaf Urban over other similar devices solely based on aesthetics. It's pretty. If I'm going to wear it every day, it may as well be pleasing to look at. I like the weight of it, although for sleeping it sometimes feels a bit much. Not a fan of gold chains, I wear mine on a leather cord around my neck, or on my wrist w/the included bracelet, which I love! Once you get the size set, it's super easy to take on and off. I've only lost it one time so far, while pulling a sweater off, and it got flung across the room. I've since tightened the strap and problem solved. Hopefully, because I'm really liking my new toy! And I especially like when people say how pretty my "bracelet" is and I casually reply that it's actually a fitness tracker;)ACTIVITY: On several different hikes/walks, I've tested the accuracy against my Endomondo app and my friend's Fitbit. Bella was impressively close considering she doesn't have GPS and those others do. My theory is that as long as I'm moving my body, I'm happy. 400 steps isn't going to be a deal breaker anyway. More importantly, I've realized that setting goals (via the app) enables me to motivate myself to do more. I find myself competing with my own history!My one big complaint: My Leaf has tracked me while driving several hours in traffic, and awarded me 14,000 undeserved steps. I drive a huge bouncy bus for a living, so this isn't a one-time problem. On such drives, I've learned to wear it as a necklace to avoid the miscalculation;( I get it. Movement. BUT I would like to be able to correct/edit the error on the app. Aside from my daily tally being off, my weekly tally (which was a surprise bonus to get in my email!) was also skewed. Maybe they will add that to future updates???SLEEP: I really didn't think I'd use or care much about this function. I was wrong. Just seeing the patterns laid out in front of me really does make me cognizant of how much, or how little, sleep I'm getting. AND I've justified a few naps this month in order to meet my daily sleep goals, haha! Furthermore, there's something to be said for the visual showing how my sleep, activity, meditation, and period all affect my stress levels.MEDITATION: Surprisingly, this may be my favorite feature. I'm not one to sit still, so the thought of meditating doesn't generally enter my mind. Until now. And since I've set a "2 sessions daily" goal, I actually will make time to stop and breathe. The shorter 2-3 minute sessions come in handy throughout my busy work days; and my husband even asks for the 10 minute "Deep Sleep" before bed. It would be nice to get new meditations every now and then, as I'm already memorizing a few from repetition.STRESS: the jury is still out on this one since there are times I KNOW my stress resistance is at a low, but Bella says I'm fine. It would be nice to have a pulse reading capability to give myself reminders to slow/calm down or just to see what my triggers are.CUSTOMER SUPPORT: Ive honestly been disappointed with the help section on the App. Yes, there are several pre-answered questions, but there isn't a place to type in your own individual question and send it off to Bellabeat's cyber gods for help. Maybe there is and I missed it?? Or hopefully that's in the works, as well.APP: the interface is clean and clear and straight forward. I love that they include Dog Walking and Bikrams Yoga in the activity list, but I'd love to see "hiking mountains" in addition to the existing "hiking cross country". It's a tiny request.Last, but not least, some people have asked if my Leaf gets text messages, receives calls, or can check emails... THANK GOODNESS, NO. I'm plenty connected enough and I certainly don't need any additional RF waves coursing through my body every second of every day. This was actually another huge selling point in choosing this product. I know progress happens, but I hope future versions continue to offer the opt out models;)All in all, I wouldn't hesitate to buy this product again, or to recommend it to all my friends!
