The bg2040 is the product i have been looking for forever. I read a lot of reviews online, where everyone has been pussyfooting around the main reason why they were looking for such a product, so here i am going to say it.
IT is probably the best down under shaver you are going to find, its light, safe, effective and very very maneuverable. I was afraid that the flat head might be a little too large for use, but its not and it has never hurt any skin down under ever. it does great on other parts of the body too.
i was so impressed with the trimmer with the preset hair combs, that though i had no intention of using it, i ended up trimming an arm and then the rest of me.
Only 1 gripe is the battery charging and alert mechanism could use an update, i don't like how you don't know what charge level its at before you get into a session, and how they recommend you don't charge until its significantly discharged. but that's something that isn't much of a bother.
