Comes with 2 viewing cones to accommodate different ear sizes.
Magnifies 8-10 times actual size.
Size "AAA" batteries included.
Light shines off to the side, not where you need it. Weak magnification, viewer too small.
My dog is always scratching his ears for no reason. The vet gave him a clean bill of health. I bought this to keep on hand to save unnecessary trips to the vet. It works wonderfully well. I even use it on family (cleaned off, of course) members to keep ear health under watch. Wonderful, useful item I have no regrets purchasing it. I highly recommmend it.
