It's no secret that I love Tenga products. I own several of their Flip range, nearly all of their Spinners, an Arte and a Puffy plus I've tried several Eggs. They're definitely in my Top 3 toy brands of all time, and honestly are definitely my recommendation for anyone who is wanting to dip their toes into men's toys.
So, one of my very first toys was the "White" version of this and I was very curious to try the Strong/Black version (Tenga's colour scheme system is one reason I like them - White is usually gentle, Black usually firm/intense). Honestly, it's not THAT different. I think I have a slight preference towards the White, but I also enjoy softer toys now. When I first started, I basically figured "Why would you ever want LESS stimulation?" but my preferences have evolved a bit.
Anyway, the Flip series is great. Easy to clean, discreet, and super fun to use. The Flip Orbs are a bit cheaper but no less enjoyable. Grab this one if you like intense stimulation while not having to worry about someone spotting a big rubber pussy on your desk )
