Along with the Wahl Groomsman beard and hair trimmer, there are

Features and Specifications Analysis

The Design

I found the American company Wahl designed their Groomsman trimmer with a great design sense.

The trimmer has a nickel-finished design with a silver colour appearance to attract the user’s eye easily.

Wahl used an ergonomic handle with soft grip pads to keep the device secure, even if your hands are wet or slippery.

The handle fits the grip accurately and feels very comfortable to make a stroke.

High-Carbon Precision-Ground Blades

The Wahl beard trimmer groomsman 9918-6171 comes with very special blades.

The blades are made with high-carbon steel with precision-ground technology, which stays sharp for a long time.

Wahl says the blades are self-sharpening, so the blade will stay sharp without any special maintenance.

Wahl included a lubricant oil to maintain the blades in case of any problems.

But you will need it very infrequently.

Since the blade is made with high-tech and great quality steel, it is literally very sharp to provide very smooth and fast trimming results.

So, regardless you have stubble, a medium beard or long hair, you will get a precise and clean trim every time without any pulling and tugging.

Washable Nose and Ear Trimmer

Wahl includes a bonus 100% water-resistant nose and ear trimmer with the Wahl Groomsman trimmer package.

Affordable Price Range

I’m unsure whether you are looking for an affordable product, but it is a super affordable device.

The package costs less than half of other beard and hair trimmers and has lots of attachments together.

We guess the main reason for being too popular is the price of the trimming kit.

We found that very few brands can provide too many attachments on a decent budget.

Adjustable Guide Combs

There is an adjustable comb with the package, which offers 6 position adjustment settings for different lengths of trimming.

This comb offers more options for styling hair and beard.

There are 3 more adjustable short, medium and long hair and beard combs for more precise trimming desire.

All these 4 combs make the Wahl groomsman trimmer super flexible in trimming.

The combs are very easy to attach to the trimmer and detach from the trimmer to replace one another.

Just detach a comb and attach another to get your desired trimming length.

The Battery

The Wahl beard trimmer groomsman 9918-6171 comes with a powerful NiCd rechargeable battery.

The battery offers a long time of cordless beard and hair trimming in one to 8 hours of charge.

Wahl says the battery will take 8 hours to fully charge and serve 2 months in one full charge.

But we found it serves less if we make frequent trimming every 2-3 days.

The promise will be fruitful if you trim twice or once a week.

The battery is pretty good, but the charging time is long.

If you are tired of 8 hours of charging, you can place it in the charge at night, and it will be fully charged after a full sleep in the morning.

Then it would not be a problem, I think.

There is another way to get rid of longtime charging is the corded trimming option in this trimmer.

LED Indicator

The device has a useful LED charging indicator to show the charging status in red light.

The LED indicator lights green when the battery is fully charged and needs to remove from the charging cord.

The indicator helps to keep the device safe from overcharging, although it will not cause any issues while overcharging.

The trimmer comes with lots of surprises.

Another surprise in this trimmer is its cordless and corded usability.

While you have enough charge on your battery, you can have a cordless trimming, and if the battery is drained fully and you need urgent trimming, you can trim with the trimmer connecting with the direct electricity.

Before using corded, you must check that the device is fully dry, or you may have a mild electrical shock.

But I didn’t find anything like this and found it very useful in corded operation.

Powerful Motor Drive

The Wahl Groomsman beard trimmer comes with a solid motor drive to provide fast and reliable trimming every time.

The motor creates a very speedy vibration and rotation to make the trimming process smoother.

As it makes more vibrations, the device creates little much noise, which can disturb a man when passing it near to the ears, or it can wake a sleepy man in the morning.

So, the sound may be an issue for someone who likes silent devices.

Travel Lock

The travel lock is really an appreciative feature in a shaver or trimmer.

The Wahl Groomsman trimmer 9918-6171 comes with a very useful travel lock system on the switch.

You will see there is a narrow red button on the power switch. Just press the red button to lock and unlock the power switch.

The travel lock feature makes the device more travel-friendly and secure, even in your drawer or bag, to protect it from unintentional switching.

Cleaning and Maintenance

The trimmer is not waterproof. So, you have to clean it in a dry condition.

A cleaning brush with the package is used to clean the trimmer head after every use.

It may take a bit more time than waterproof devices.

I recommend thoroughly cleaning the trimmer head after every use to keep the trimmer sharp and perform well in the next use.

This may be a downside of the device as it is not water resistant.

But we should keep the price in mind. We cannot expect more on such a budgeted device.

Performance of Wahl Groomsman

The trimmer itself is a very affordable device with lots of attachments.

But we found a great result without the attachment combs to have a stubble look with the trimmer.

When we used the adjustable combs on the trimmer to have different lengths of trimming results, it took several passes in the same place.

But when used to completely remove the beards from the face and have a stubble look, the trimmer provided a very sharp and fast result.

Since the trimmer blade is very sharp and self-sharpening, you do not need to take many strokes while using the device without the combs.

The trimming kit is very useful for creating perfect edges in the neckline, cheek line, and jawline and shaping sideburns.

You can easily make a stylish outline fashion in your beard with the trimmer.

If you have enough time to pass the device on your beard or head hair several times, you can use the combs too.

But we do not recommend it for long hair trimming.

It is recommended to have it for a stubble look or outlines.


Wahl Groomsman beard trimmer comes with a travel pouch to carry the device safely while travelling.

I found the bag is pretty good for carrying every part together for a trip.

The device has a very intelligent travel lock system on the power switch to lock the power in the travelling time to protect the device from automatically turning on.

The package comes with a worldwide voltage (110v-240v) charging adapter which allows you to charge your device from other countries.

This must be a great feature for an electric device.

You might be thinking that your old one does not support the worldwide voltage, but I mentioned it supports.

There is no confusion that the older model version did not support universal volt.

But the new upgraded version does support worldwide voltage.

3 Year Warranty

The Wahl beard trimmer 9918-6171 comes with 3 years of warranty from the actual purchase date.

Within 3 years, if you find any workmanship defect or it stops working like before, the Wahl brand will repair or replace your device without any cost.

But the warranty will not cover if your device breaks or damages by accident, misuse, or abuse.

So, it is recommended to handle the device with care.

60-Day Money Back Guarantee

Wahl American Corporation offers 60 day money-back guarantee for this product.

If you do not find this satisfactory or have any issues, you can return the product within 60 days from the actual purchase date.

Wahl will give you the full money back within the timeframe in this agreement.

So, buying this product is really very secure for men who are confused about the product.


  • Long-lasting self-sharpening blades.
  • Lots of attachments.
  • Cordless+Corded trimmer.
  • Lots of features.
  • Soft grip pads and contoured head.
  • Travel lock.
  • Good Battery quality.
  • Super affordable.


  • Not good for long hair.
  • Not waterproof.
  • A bit noisy.
  • Full charging time 8 hours (corded+cordless device, though).


The Wahl beard and hair trimmer groomsman 9918-6171 is a second-grade beard-trimming device in a third-grade price range.

So, it is comparably good according to the price range. But it is not sturdy like the premium 1st-grade trimmers like Philips Norelco Multigroom 7000 or Panasonic ER-GB80.

It works well for short beard trimming without the guide combs. You can use the guide combs with enough patience to make several strokes in a place.

This is not waterproof, so it is a little hard to clean and maintain. But we should keep the price in mind.

If you are okay with a second-grade beard trimmer and do not want to break the bank, try the Wahl Groomsman beard trimmer.

One comment

  1. The only multigroom kit that comes with a very little budget. Its built quality is also great while comparing to same range products. The powerful brand is very confident with this product that’s why I bought one since it provides money back guarantee and 3 year warranty. I got my best product thanks. The only obejection is takes long time for full charge, but for supporting corded feature, it solved its problem. good man!
