This is kind of belated, but my advice is that I don't think that you will be disappointed! The pump has saved my life. I have been using it since 1994 and am still going strong. I had the same problem with Viagra etc.
The pump (osborn) and rings work well for me Steve, and has for the past 18 years. It is different and you have to be patient with it, however who wants to go without sex. It has been great for both of us! It has saved our sexual lives.
