Review wire butterfly guitar picks?

Has anyone tried the wire type butterfly guitar finger picks (on ebay) ?[#121077058825]. I am a beginner and like the finger picking style. I drop my pick a lot and would like to hear from anyone who has tried the wire butterfly picks on ebay. The plastic wrap around picks look clumsy to me. I am also having trouble getting my frett fingers to toughen up so is there something I can use on those finger tips to help?
