I have tried a LOT of rabbits, my hands down favourite is the Mantric (without shaped ears) one. It has deep, rumbly, penetrating vibrations, a pefectly shaped shaft for G-spot stim and loads of flex at the base of the shaft and “ears” for a fabulous close contact pressure at whatever angle. I think this also makes it fit a lot more bodies than a lot of other rabbits do. No question, my top rabbit.
I have had two thrusting rabbits, one from a high street store 20 years ago, which I loved but the thrusting motor wasn’t strong enough to overcome orgasmic clenching 
. The second was a Fun Factory one, the motor was very strong and didn’t fail to perform but I didn’t get on with other aspects of it as well.

Can also answer queries on quite a few other rabbits if you have any 
. For example, the FSOG real feel - great shaft, hate the ears, but if your dearly departed favourite had similar ears you might love it. The Mon Ami - great vibes, excellent control system (better than the Mantric), not enough flex for a good fit to hit all the right points for me.
