Some sessions you want to put in the work. Others you just want to let go and feel everything. The Master Bot is built for the second kind. You slide in, hit a button, and let the machine take over completely. That is a different experience than anything you can do by hand, and once you feel it you will understand why guys come back to this one.The hollow TPR sleeve is lined with rows of textured ticklers that press and drag along you as the stroker cycles. That internal friction is the whole point. You can ride the two speed settings to find your pace, or you can add your own movement on top of what the motor is already doing. Layering those two sensations together is where things get genuinely interesting. The sleeve wraps tight and the texture does not let up, so every stroke delivers something.This is not a complicated product and that is not a complaint. It does one thing and does it well. You lube up, you slide in, you press a button. Everything else takes care of itself. If you have been curious about what an auto stroker actually feels like, this is an honest and straightforward way to find out.Product DetailsMaterial: TPR sleeveVibration Speeds: 2Power: Controller switch
