Query: way to time consuming to get a close shave

I was very excited about getting this product after reading several positive reviews. I was, however, very disappointed after several unsuccessful uses. The trimmer works fine, but the shaving process is near impossible to do in a time efficient manner. It only gets a close shave against the grain (which would be fine but if you don't go against the grain it hardly gets anything done). It also takes way too many strokes to get a close shave in one spot and this leads to irritation post shave.After spending a half an hour in the shower I was able to get a close shave on the abs (skin irritation included), but the contours of my chest were near impossible for this thing to properly shave.After all the reviews of how easy this thing is to use I am curious if I got defective one or if there is something I'm missing about how to use it, but all in all, this product has not done what it is supposed to for me.
