hi mommy24: sorry haven't been online in a little while , been moving into our new house , yes to your question about the zapper , it does work well I have avoided alot of colds and the flu since using it ,you can find some reasonable ones on line , it cost about the same as making one yourself ,without the hassle , according to hulda clark she says that using the zapper every day for a month will reduce candida to very low numbers ,I have not tried it for that yet , but maybe very soon , I have started a strict candida diet about 3 weeks ago and am feeling better , I am going to try coconut oil soon to help keep candida in check
