I had the XL-1000 Deep Throat Maximizer before I bought the DP-4000.
I bought the DP-4000 22/3-2013 and has reglebundet weekly used pump.
The advantage of the DP-4000 is that I can set the values â€‹â€‹I use.
For me working DP-4000 very good in both length and thickness.
When I have the opportunity to vary the vacuum pressure and the times
I get the maximum length and thickness increase.
When I can set the values â€‹â€‹myself I found once the values â€‹â€‹ stretcher best and that's comfortable.
I have tried to use my old pump but notice right away how much better the DP-4000 is.
For me it is a very good product that has worked perfectly all the time.Click para ver todos los testimonios
