lovesense

Im new to caming and for 2 months i have worked without a lush. I dont need to tell you that it was hard to make money without it. Now that I have one, I try to scan the QR code and it is telling me that this is not a lovesense QR code. I dont know what kind of company they are but how can I buy...

So I was thinking a Lovesense or some sort of tip-activated vibrating device would be great for my show, but under the conditions that nothing goes in my butt and view of my cock isn't obstructed. Is there any sort of cock ring that responds to tips or a way to rig an existing device to that end?

Title says it all. What have peoples experiences been with bluetooth/interactive toys? They're quite expensive. How well do they last, what problems have you come up against, do you think I can break even on the investment of buying one easily or would it take a while? Thanks, Gummi
