I love the duel end and how many details were put into this. I'm just a beginner when it comes to dildos, let alone glass ones, and I love it. It's simple but very fun! I think it's perfect for someone trying to get a feel for things or trying something new. I used it with a mix of my vibrator and had an excellent time! My hubby and I tried it out together when I first got it, and needless to say, we both enjoy it very much. It's good if you're into dabbling into sensory play as well, but it doesn't take long to warm the glass up either. I just tuck it under my thigh while we're getting ready to use it, and by the time we do, it's perfect.
