Honestly i dont know, i have had noone complain, i do have most of my css as percentage so it should reduce down and if not i can fix that.   I dont even own a mobile device of any kind and i dont usually code for mobile.  All i can say is if you want to try it out, if it works great, if not ill try to fix it so it does, if not ill give a refund.  Thats all i can do :)
