Okay so it seems to be one of those AV Vibrator Wands with an adapter sleeve for the penis. The adapter seems to be this one:

(Pretty sure you can find it on AliExpress for cheaper)
For the wand to vibrate according to the beat you will need one that has Buttplug.io support. I recommend checking out the IoST Index for this (this is also a great website to search for other interactive toys).
I have personally tried some penis vibrators in the past. They feel interesting but not entirely pleasurable. Yes it stimulates and makes you cum, but not all that satisfying as compared to stroking. I think it’ll be very different if you let your partner use it on you, though.
I still recommend one since it feels completely different to use it hands-free. Magic arms aren’t huge, they are generally under 10 inch and can be folded and stored very easily. But I don’t recommend buying the official Handsfree Mount from the Handy. I think they are overpriced and prone to fail. You can easily build a handy mount yourself following this recipe.
The OSR2 must be mounted to the desk. They generally comes with a 3D-printed desk clamp that is attached to the back of the unit. They are still compact and can be stored away into the drawer together.
Nah. You can use Funscripts on any stroker toys. They aren’t exclusive to the Handy. And if you want to use a stroker script on a vibrator, there’s always a method to convert them.
You can strap any toys to the Handy as long as they don’t exceed 400 gram and is in a cylindrical shape. I personally don’t like the Handy’s sleeves and have been using it with onaholes, the MIL-MIX+ 2 for example.
Which is to say it’s unnecessary to buy all their sleeve at once. Go and give the default sleeve a try. If you like it, buy more. If you don’t, try strap other sleeves you have onto it and see what works.
