I would agree with the above, except for the I, go with the Hydro Magic (I2 Black Handle and has a lever to open to clean) an excellent razor. I have had two different I1's with the beige handle, both far more aggressive than most of the model E's, or G's or L's.The E, G, I and L are all great shavers. If you're looking at an adjustable, you'll want to look at the M model.
