The battery life seems to have dropped to an unusable level. A fresh set of Energizer Max alkalines die in a couple of weeks with no lock activations. Wifi router tells me he connection qualiy is "Great". I asked under the "questions" tab for strategies to fix this and they repeated the standard response included in other locations on this page. It would seem that the battery life on these units is not as advertised and there are some significant flaws that aren't being disclosed. Too bad, it looks nice and has a lot of promise, but I would not recommend anyone purchase a Weiser product.
