Well, what can I say, when I originally purchased the automatic inflating dildo and harness, I didn't really expect much, but it has turned into one of my favorite toys for lasting reasons. When I have it deep inside and start to inflate the cock, it is purely amazing. I haven't ever felt anything quite like that, and it's also great for beginners to use for training and practice to step up to bigger and badder toys. It has a strong vibe setting, and it actually inflates pretty large. It could be dangerous if you push too much, so be careful but enjoy this toy to the fullest.
