Bouncers and motor development?

JK
I'm debating whether to get a jumparoo or something similar. I've read that it can inhibit motor development and better for them to explore without being restricted which makes sense. But also as my little guy gains more and more weight and wants to be bouncing more and more, I'm think as long as in moderation (not in it too much) it may not be bad thing either.
Anyone have any solid research that I could review on this? 
Thanks!
