if your gaining with the phallosan then no but ive tried both, with the silli stretcher you get more tension with the belt supplied ,more angles to stretch you can stretch between the cheeks ,right ,left side, straight up and down left and right you can hang with it and if you need even more tension there is a hardcore leg strap sold separatley and its simple to use ive used it today between the cheeks 4 hours straight in comfort with a good pull causing no discomfort just a nice dull ache so the answer really only you can answer if your gaining with the phallosan why waste money if not the the SiliStretcher is superior in the ways I outlined best of luck
