What customers say about "Key Specs"
Philips Norelco Bodygroom Series 3100 (BG2034) Shave and trim with back attachment
  • This single item has replaced a razor, foil shaver, and clippers for my trimming needs. The clipper sides of the shaving head do a great job at cutting longer hair and the foil center shaves gently and smoothly.
  • The height guards are great and the small size of the head allow it to be maneuvered easily. I love that I can do everything with one tool instead of the 2-3 I had to use before.
  • The back attachment has 7- different locked positions, allowing multiple angles to get those hard to reach spots. It comes with 3-combs for different lengths[1/8"(3 mm.),3/16"(5 mm.),and 9/32"(7mm.)
  • It comes with 3 comb attachments that are much like the kind that comes with a hair clipper. So, for getting very close you’d use no comb, and/or you could choose comb if you want to just trim the length of the hair.
  • requires replacement of the foil every six months or so or it will begin to eat your skin!
Philips Norelco Bodygroom Series 7100 (BG2040/49) body trimmer and shaver
  • 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.
  • I like the sharpness and cutting of the blades. I would prefer a longer handle, maybe 2 inches longer The linger handle would make shaving my back much easier.
  • The Foil replacement head started to rust after few months. Otherwise it was a Very good product.
  • wish the length of trimming guard was a tad greater what is available on the trimmer shaver is a bit short for my beard... other then that works great!!!!!
  • However my only complaint with it is that you must go slow or you will easily cut yourself with the blades on the trimmer side but other than that the razor is great.

What customers say about "Size & Weight"
Philips Norelco Bodygroom Series 3100 (BG2034) Shave and trim with back attachment
  • I was a bit intimidated by the size of the razor and that it was for men, until I felt it against my skin. It was very smooth and effortlessly removed the hair
  • Battery lasts a longtime, convenient to use in shower, light weight and comfortable to hold.
  • Very light weight and pleasing design. Had issues with pulling hair instead of cutting it.
  • This is a much better trimmer than the one I owned before, it's light weight, safer and comes with more features.
  • The weight is balanced and so it feels nice in your hand.

  • Design of the product makes it easy to handle on the body.
  • Is very easy to use like the older models but this one got a firm touch but also gentle enough to use every 3 to 4 days.
  • IT is probably the best down under shaver you are going to find, its light, safe, effective and very very maneuverable.
  • Its not heavy and does an absolute awesome job. I was amazed at how close it shaved.
  • Higher quality construction than the mangroomer line of products which are made of cheap plastic and don't work well. Easy to use.

What customers say about "Features"
Philips Norelco Bodygroom Series 3100 (BG2034) Shave and trim with back attachment
  • I only used it for armpit and bikini area hair removal, but i'm sure it would do a great job on legs or any other below the neck area of the body, as it warns to only use below the neck.
  • The unit was easy to take apart to clean and it snaps back into place easily. I used it without a guard, but it has 3 guard combs for longer hair, a cleaning brush, a charger and an extended handle for use on your back.
  • The clippers on each side of the shaver will shorten the hair then the shaver in the middle shortens them some more.
  • Special design prevents nicks and cuts. It does take a little time to know your own body, like the direction of the hair. to get that real good cut you are looking for.
  • I really like that is water proof, can use wet or dry. Good for any area BELOW the Neck, back and shoulders, under arms, groin, and even legs for that real; smooth feel and look.
Philips Norelco Bodygroom Series 7100 (BG2040/49) body trimmer and shaver
  • he trimmer settings and cut do a good job of getting the right cut and length. The shaver head provide a close comfortable shave. The unit is easy to clean and charge.
  • 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.
  • As advertised it works very well with lather either trimming or saving in the shower and cleans up very well.
  • There are no attachments to keep track of, yet it allows you to shave and trim anything in any way you want.
  • It's very convenient being able to flip the groomer over to shave or groom without having to change or remove parts. Battery lasts a long time for me but I'd prefer it wasn't nickel metal hydride since you need to wait until it completely discharges before recharging it.

What customers say about "Power"
Philips Norelco Bodygroom Series 3100 (BG2034) Shave and trim with back attachment
  • Clean up is easy and the charge lasts a long time!
  • It charges in its base over-night and it says it can be used for 50 minutes without a recharge. I did not time it, but I know I used it for very close to an hour without charging without any trouble.
  • I really like the battery indicator LED, as well as the sleek charging stand that it comes with.
  • Battery life is seriously impressive and lasted through an entire top to bottom trim.
  • however after about 1.5 years of use the battery gave out. and morelos does not sell replacement rechargeable batteries for this product.
Philips Norelco Bodygroom Series 7100 (BG2040/49) body trimmer and shaver
  • Charges fast, easy to put in and out of charging stand.
  • This has everything a guy needs which is a close shave with minimal irritation. The charge lasts a long time - hours and hours. I use it all the time, satisfactory all the way.
  • It charged up quickly, and the cradle that comes with it is practical. The trimmer does last as long as advertised.
  • The battery charges quick and lasts a long time. It's easy to clean and convenient to store.
  • 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.
  • Battery stops charging after about a year and then you are forced to toss the thing since you can't replace the battery.
