I trained Dipsy in under 2 weeks. I got him from a rescue September of this year, but turned out to be very, very aggressive, both inside and outside of his cage. In desperation because he was really hurting me, scaring me and upsetting my daughter, I started to look on the internet for how best to manage such aggression. I have had bunnies before with aggression problems, but nothing on this scale. The one thing I kept seeing mentioned was the clicker training, and how effective it had been. I therefore decided to give it a go and have never looked back. I see now that Dipsy was such a angry bunny , because he was so bored and mentally unstimulated, and this has completely changed him. He now has free run of the house all day, because he no longer attacks us, and is really good in his cage as well, when I am cleaning it, or just doing his food and water. I would definately say 'go for it'. Dipsy now comes when he is called, I can make him sit and stay, which especially when inside his cage is just fantastic, and can actually difuse an attack. Sometimes, I can tell just by looking at him that he has got his 'grumpy bunny syndrome, but am now finding that by making him sit and stay, and then giving him his treat, makes him so happy that he forgets all about being angry. He was terrible and always attacking us when we were trying to catch him to put him back in his cage, but now I call and click him, give him his treat, and he sits in his food corner, waiting patiently while I get his food together. I can now also stroke him and make a fuss of him in the cage. without him biting me. Have you got any specific reasons for wanting to 'clicker train' your buns? I got a clicker for a pound, and the book that I enjoyed most was one called 'Clicking with your Rabbit and I got that off ebay. You will have loads of fun with your buns if you decide to go ahead and do this, and no, you wouldn't be wasting your time, because Dipsy is no longer aggressive.
