Review (1/5): Missed the boat
I purchased this shaver based on my test of a much less costly Norelco rotary shaver. I used a Panasonic, my third, and the trimmer blade came loose. Panasonic service was nonexistent so I decided to switch to the rotary after testing a razor my son no longer needed. That gave a great shave but did not have a trimmer. The only trimmer unit was this expensive SmartTouch XL. This, by the way, is not a wet and dry shaver. Knowing this, I decided to give it a try anyway. For the price, I guessed it gave a really good shave. Not! I have to work really hard to get the little nubs. Sometimes a trimmer helps to get the persistent hairs but the trimmer is a flip up item that does not lock in. It can only be used when applying pressure to the hinge or it flips shut. The trimmer also does not get close to the hair base, only trimming longer hairs. Forget any ear hairs with this trimmer.
In summary, this was engineered by a technician who must have a full untrimmed beard. If you want a rotary razor, get the cheaper ones or try another brand. I would return this but I waited too long hoping for the super shave that comes with time. After almost nine months, I am about to give up on that hope.
