The "Spider" as we call in in our house is an amazing innovation, taking aching arms out of the equation when it comes to a masturbator! Fantastically innovative and tighter than a fleshlight causes him to give it 5/5 stars, but I only give it 4/5 stars for quality.
I love mine! To prevent tearing while using it, letting it warm up helps.
The Spider definitely feels more realistic than any Fleshlight I've tried (I have both).
