Well Kev ... this is from patients experiences .... (been nursing for 7 years)... they work but not as good as viagra ... with these other medications it does take longer to have a second erection ... the turn over time for viagra is shorter ... the lasting effects of the others are longer .. so they both have there pros and cons ... most doctors can give you a sample to try before purchasing them .. the never drugs are a bit more expensive .... Happy swinging
