This actually did what I've been hoping for
After a couple of tries this actually did what I've been hoping for for years, or at least about a year. Amazing.

An erection in 2 to 3 minutes
Even at the lowest frequency it will produce an erection in 2 to 3 minutes when used perpendicular to the shaft. I have only had it for 12 days but at this point it has reduced my loss of sensitivity. One caution: do not over stimulate.

Worth the wait and works great
I have worked with Stiff Up for about a month. I was able to achieve a strong ejaculation and orgasm with this device with a little experience and experimentation. In summary I'm really impressed with this product.

I followed the instructions and it worked 100%
I've had a broken fifth cervical spine for 20 years now. I stumbled across an article about Stiff Up and decided to give it a try. I followed the instructions, and it worked 100%. It really helps, thank you.

I left a one star review. Then it worked.
I tried a number of times and the vibrator failed and I left a one star review. But after continuing to try I have gotten it to work and it was amazing.

I was very happy to report this worked
I have an L1 L2 incomplete spinal cord injury. I do not have an issue with erections, but I did have great difficulty with orgasms. I've tried a lot of different things, and I was very happy to report this allowed me to achieve orgasm.
