Reddit mentions of REMINGTON WPG4020US Smooth & Silky Body & Bikini Kit, White/Pink

It depends on what kind of electric razor it is. If it's a bladed edge (like the kind you shave your head with) it's not possible to get completely smooth. If it's a foil razor (similar to a guy's facial razor) then you can get almost completely smooth. I only learned about the latter when I bought a razor that has interchangeable heads of each kind.

Edit: This is the one I have

I trim with an electric trimmer, like this one (http://www.amazon.com/Remington-WPG4020A-Body-Bikini-Grooming/dp/B00BB5YI0Q/ref=sr_1_7?s=hpc&ie=UTF8&qid=1427510122&sr=1-7&keywords=trimmer+for+women)

I don't like to shave because I feel like it's a lot of maintenance, but keeping tidy without it letting it get overgrown is easy with a trimmer. It also usually has a blade-guard, so it doesn't nick or get super short/uneven.

Just so you have this information:

I have always had ingrown hair issues with shaving, and I used to get waxed by someone who was amazing. When it grew back it was softer and not all itchy and painful like when you shave. BUT that was when I was in college. After I graduated I moved cross country. I could never find someone as good and as inexpensive as her again and then it was HIGHLY unpleasant, nobody would listen to me when I said I wanted to keep most of the hair on the front where I thought it should grow and just get rid of the "extra" stuff around the edges, and I stopped doing it.

Now I just trim things and think it's fine. I bought one of those electric trimmer things from Target in the razor aisle, ~$25. Not the mini one -- the bigger one that's advertised for armpits. This one.

I've used a couple. One of them was a Clio - I liked the shape, it made it easier to hold. Eventually it just shortcircuited.

Now I have one by Remington that I can't find an example of, but they have this one that looks pretty close. It does a good job and since the head is smaller than the Clio, has more precision (but takes more strokes). Remington is a very reliable brand from my experience - 90% of my bathroom appliances are by them.

Both of the shavers I've had are wet/dry which I think is really important. I think it does a little bit better job dry but I'm too lazy and usually just do a bit of trimming in the shower when my conditioner is soaking in.

If you only need it for upper lip, I'd say get a smaller one like this, for instance. I have it and it works pretty well, but I upgraded because I needed one with a bigger head. I still use the smaller one on my upper lip.
