The nickel finish gives it a neat smart look and makes it easy to clean.

What the Reviews Have to Say

The best way to tell if a product is a good buy before you actually purchase the product is by looking at the unbiased reviews people who have bought the product write to help others make the decision of whether or not this beard trimmer will be right for them.

In the case of this Wahl beard and mustache trimmer, the sheer number of reviews shows that it is an extremely popular trimmer among men who have beards and/or mustaches. Here are some of the things actual users liked and didn’t like about this particular trimmer.

Main Complaint

The main complaint that some users have regarding the Wahl 9918-6181 beard and mustache trimmer is that the guides are not made of the sturdiest plastic and therefore, some users have experienced breakage and the guides falling out during use.

While this is certainly not a regular experience for most users, it does occur on occasion and therefore needs to be mentioned.

What Users Really Like about this Beard and Mustache Trimmer

The positive reviews for this trimmer outweigh the negative reviews by quite a wide margin, with the majority of the users finding the Wahl 9918-6171 to be everything they could want in a beard and mustache trimmer and evem more.

Here are some of the features users were especially impressed with:

  • The good quality of trim they can get with this inexpensive beard trimmer.
  • How quickly the trimmer charges up and how long a charge lasts.
  • The fact that you can use this trimmer with or without the cord.
  • How easy it is to maintain the trimmer.

Overall, the majority of the actual users find it an excellent product for a very low price, giving them more value than they expected for their money while giving them the kind of trim they are pleased with.


My advice can only be based on how I am using it. For me it´s good because I use it as a second trimmer. I have a thicker coarse beard and the quality of combs is important for me and that´s why I have it as a backup trimmer for outlining and body grooming.

It has lots of good features where even some of the even more expensive ones fail and the price certainly makes it very attractive. Also, with a 3 year guarantee you can´t really go wrong.

If you are just starting to grow a beard and need a low budget trimmer, then this would be a good option, just be gentle with the attachments. On the other hand, if you can afford to go up in price or you maintain and trim your beard regulary, I would suggest you look for other choices available in the market.
