I really love the cloudy sky dildos. I have several now, of all three sizes, and I'm aiming to collect the lot. They're aesthetical nice, though the blue is definitely my favourite colourway. The silicone is a good blend of flexible and firm enough give so you don't feel like you're being impaled, but still firm enough to give you something to push against. Plus, they're well balanced, with a good, wide, suction cup base that is really stable once you place it. I'm certain they'd work well in a strap too, though I haven't had the opportunity yet.
Good product for what it is, does the job perfectly. Material is skin like, meaning it can be a little uncomfortable using without lube.
