I have always seen the Russian Zapper made of stainless aka nick named the sputnik as the ONLY electronics that WORKS when used properly 3X in a row. The medical grade ECCOMED is 100% pure trash product an used in eropean hospitals; it leaches toxic metals into the intestinal tract.
I don't sell them anymore because of one main reason:
The factory must put an expiration date on the package of 1 year. This means they may be 6 months old or older by the time you import them from the factory wharehouse. Then you have a few customers that send them back because of the date..We know they still work even 3 years after the expiration date, but customers will be customers., etc., etc. so we got tired of the few that want to complain about anything that they can find to complain about and we also don't like importing a russian black market item; so we stopped.
The only source I know of out of country that resold them sent me a bunch of Pre-Used Ones, I will never suggets anyone buy them from the turner clinic, even if they don't send out used ones anymore, you could never trust anyone like that, not ever! When you buy from the internet, you never know what kind of trash your going to run into, your always taking a risk.
I personally have none, but highly believe they should be used once per year.
