what is the best auto trimmer ????

my buddy is looking to buy an automatic trimmer but he wants on that will trim the bud nice and close but not waste good bud.he wants to get the best one the first time because they are really expensive

The best automatic trimmer is you...

Seriously, the trimmers are not going to be able to get in between and cut out the leaves.

yes i am aware but it will cut back on time so if you have any idea of witch one is the best i would like to know.cause i am pretty sure that he is aware that he`s better than a machine.i know that there is the bowl trimmer that is smaller than the other model anyways any help would be nice
