Question about the Charlize rabbit

I love the vibrations from the shaft but the clitoral arm vibrations are really weak (to the point that I can barely feel them) and a bit on the buzzy side. Is this just a downside of this particular toy or could mine be faulty? One other reviewer said the same thing as me, but there are only 4 reviews in total, so it's hard to compare.

I was thinking of exchanging it for the desire rabbit, but I love everything else about it so I want to make sure it's not a faulty one. Thanks!
