The guys behind Wakemate have already stated publicly that the battery lasts 2 to 3 days (actually 24 hours) depending on your sleeping patterns. The reviewer said that the apparatus ran out of juice at the end of the third day. It doesn't take a genius to realize that he should charge the damn thing every second day. Would you NOT (on purpose of course) charge your smartphone on the second day, when you know that it just doesn't last the full third day? Instead of charging the device every second day the reviewer decided to keep pushing for the three days that he fully knows the device doesn't last for him and his sleeping patterns. Battery estimates are just that, estimates, and vary greatly depending on the amount of usage a device gets. The reviewer knew that that thing is not lasting three days for him, and the review is a sarcasm ridden piece on how he was fooled to think that it would when the website clearly states that it might not last 3 days for everyone and actually depends on your sleeping patterns. Read the review again and you'll notice that the Wakemate does have all those things you want in an analytics package, but the reviewer dismissed it with a wave of sarcasm because according to him the only use for analytics and tags (for events, as you mention you want) are to tell you that you had a "crummy night." You will also notice that he states that the Wakemate works with YOUR movements as opposed to the movements of whomever you're in bed with, but he says this in a way that it's easy to misinterpret it the other way around. Immediately after the fact he starts complaining that the alarm might wake your significant other, which any alarm will do. My point is not that the review speaks negatively of the Wakemate, I don't even own one and really don't care much about it, but the review was completely lopsided. It belittled every good thing the device has (the analytics, the tagging, the raw data, the fact that it works even with other people on the bed, etc) and made a big deal about something that not only is not a bug deal, but works exactly as is stated by the product manufacturer. Other than the pairing issues the reviewer had, the rest of the review read like a sarcasm ridden payed "anti-advertisement" against the Wakemate.
