I have the Deluxe magic wand and the USB fairy wand and its the best 2 toys other than my Rockbox I own, its an absolute tybox essential and your wife will love you forever!
Its definitely better than any rabbit she will own with the right attachment.
Buy the G-tip attachment too as is blows my mind every time,
I too adore my rabbits and never thought anything would comes close; Im also a bit of a power queen and the wands give me both.
The gtip attachment will be perfect for her if she loves rabbits, its perfectly shaped for internal and outer stimulation of G-spot, clit and anus; what more can a girl want.
I have my most powerful squirts using this G-tip its worth every penny to buy with whatever wand you buy, the wands have the extreme rumbly power and tip transfers it to the right places.
I also have the mini wand and as Gem says its on offer for £10 thats powerful too but not as powerful as the deluxe wand.I will have a review coming soon on the mini wand.
Heres my review of both items it may give you the info you need with lots of photos.
