OK, the price was more than I was expecting to spend - but it was well worth it! I have two other sex machines that require time to change the settings. I can adjust the speed but I can't adjust the depth without changing thumb screws. I can change the settings instantly with this system just by touching a button. The really cool thing is the programming. This thing comes with programs built in and I can add my own. I created my own program in less than 5 minutes and it cycles through the patterns I love most. I just select my program and press run, the Shockspot does the rest. Thanks Guys!
