My go to toy when I want to warm up for an extended anal play session. My rating is based on that use, as a warm-up toy, if you’re looking for an orgasm machine I'd look elsewhere. A flexible shaft and seven functions give this toy plenty of versatility, i.e can be used externally to stimulate cock, balls, nipples etc. It has its drawbacks thou. First, it's TPR silicone, not pure silicone, so there are hygiene issues. Second, the button configuration makes it easy to turn off accidentally.
