CV boot clamps - need some info

I just got some ""Universal"" CV Boot clamps today. But they suck i can't get them tight, Can someone tell me whats the easy boot clamps to put on?
Please send me a link to some CV boot clamps that were easy to install or a part number..

Thanks.

I just used a hose clamp on mine... Probably not the best thing to use but it worked. lol
