Let me preface this by saying I like BJ scripts more than anything else.
I got a syncbot back in October. I used it twice, and then never used it again. I honestly didn’t even want to use it the second time. At first I stopped using it because “up and down” is important in any script including BJ scripts, and it doesn’t do that. Instead it just felt like nonsense. Then after hearing about how the inner sleeve can not just tear but they expect it to tear once a month, I am not putting my dick into something that has the potential become a large electric pencil sharpener at any given moment.
I recommend reading this thread before you make a purchase.
