I have the Fun Factory kit too with the only review so far 
. I struggled to keep the feedback within the word limit there is so much in there and it is on a good discount at the moment. The Manta is good for couple play as it has a nice big handle and looks pretty, although for some, slightly larger ‘wings’ may have been better.
If like @Candace1 you’re into femdom something like this sounder is absolutely amazing. Great for your guy to use alone too.
