I bought this yesterday 07/06/18, I was probably in the one aisle for 30 minutes or so reviewing, contemplating what to buy. I finally chose the smooth and silky trimmer WPG-4020. Tried it out today, just dry testing, and I love it, can't wait to try it in the shower. I have no cons but I do wish this was a on a charging system and not a battery, never know when the battery is going to stop, like in mid-shaving while in the shower. I guess keeping some AA batteries in the bathroom will suffice. Before I go, just wanted to say that the dry trimming I did today was a very smooth shave.
