Do NOT buy Doorbell

Wife has been telling me about this product for some time so I read multiple reviews and I decided to buy for Christmas thinking "by now they have probably worked all the bugs out", so went on amazon and got it, (bought the mounting agle device too), read all the instructions, charged it and installed it, wired it to my existing doorbell, well it is a disappointment, DISAPPOINTMENT, had to say it twice, first the battery does NOT stay charged despite the fact that it has a constant WIRED connection, 2nd when the device "alerts" you there is someone at the door by the time the appication "connects" to the device people are gone, so it is false advertising when the commercials show you talking to "the perpetrator", 3rd when you are finally able to connect to the device and since now it is too late to see who was at the door you attempt to look at the "event" it then states its loading and it takes again up to 30 seconds, 4th for no reason at all it will disconnect from the wifi and there is no simple way of re-connecting other than unstalling the device, pushing the orange button (which by the way does not always work so you have to go to the next step and do hard reset) so instead of adding automation to my house it has added more work, DO NOT BUY THESE PRODUCTS
