In my case it was the battery swelling and the beginning of the end . Check the back for fine cracks and don ' t charge if you find any . <| sep |> I personally consider them to be entirely useless , but ymmv . I ' ve never used one and have lost plenty of weight , obese friend of mine has one and in the same time has lost maybe 20 lbs ? Mostly because she just increased her walking and is eating better 21 day fix . ugh but doesn ' t really have any awareness of how much she should be eating in general and of each type of food . I ' d say that downloading MFP and buying a food scale would be a significantly better investment . I ' d suggest OXO 11 lb scale myself . <| sep |> I have been to all those , and I am struck by how shallow the faith of most of the deconverts is . And I rarely read apologetics anymore .
