I got one supplied recently on perscription from my urology department whilst discussing my ongoing ED issues ( manual one not battery but i imagine the operation is the same) i alreaady have a SOMAerect from imedicare but figured that its not going to last for ever so accepted the offer of a spare.
My thoughts - it works well, easy to use and i think its a bit more "gentle" on the tackle than than the SOMAerect as it seems to vacuums a bit slower
However i have been using my SOMAerect for 5 years now and am more used to it so will carry on with it till it breaks, this isnt a negative comment just they all have a 'knack' to get the best out of them and im more used to the SOMAerect
