We have the Stronic Real as well (My Review). It’s a lot of fun, though I have to admit that it doesn’t get used a huge amount any more (our toy collection outstrips our sex drive by quite a margin 
). It’s very jiggly, rather than straight in-and-out thrusty like a bigger sex machine, but Mrs Chimp still enjoys the sensation. 
Lots of lube helps keep the movement smooth, and gently resting a hand on the end stops it from making a break for the door.
And it doesn’t vibrate. It has magnets inside that throw the weights back and forth across the length. (don’t use with a pacemaker 
)
