Mate i had the same problem as you,i got a snap gun and i couldnt for the life of me use the bloody thing so i put it in my box and thought what was i think buying that bloody thing,,But i wouldnt let this thing beat me so i got it out and practiced till i could use it..
Now i couldnt live without it,its a must have...
So dont give up on it...they come in VERY handy...
I cant always do Yale X5 by hand and i find them hard they take some time...But with my Snap gun they are not a problem at all...
So practice practice practice practice practice...
