      for the love of god just don’t buy it


      i didn’t buy this razor. my brother bought this razor. it’s currently half past midnight. about an hour ago i heard this razor turn on and assumed my brother was shaving. kind of a weird thing to do at 11:30pm on a tuesday but to each their own. however, after about 10 minutes of this consistent buzzing i thought, “ he good?” so i proceeded to see if he was, in fact, good. turns out he’s great! he’s also not even awake. he never turned on this razor, this razor turned on itself. and i have yet to successfully turn it off. i banged it on the floor in rage a few times and the clipper fell off, however the razor is still going strong. so now i’m sitting on the floor with this razor next to me, waiting for the battery to die so i can go to sleep knowing that this piece of garbage is dead and gone. i don’t even care if anyone reads this review, i just needed to rant because i have an 8am to go in the morning and this razor is preventing me from fully focusing on the work i waited to do until the last minute. also, in the (approximate) ten minutes it took to write this review, the razor has still not turned off. i have been listening to this beautifully gentle hum the entire time. my god. don’t buy this razor. that is all.

      Not as good as it looks

      I've used a $30 Philips-Norelco groomer for several years that's finally falling apart on me. When I went looking for a replacement, I figured: why not spring for something a little nicer? Good reviews & design led me to this Wahl model. It definitely feels VERY solid and sleek in the hand, and my first use went well enough. However during my second and third attempted uses, even after oiling the blades, I experienced a RIDICULOUS amount of tugging on my beard hair. I have to cut MUCH slower than before, and it's PAINFUL. On top of that, the plastic blade guards you attach to set your cut length are both (a) inconvenient, since you need to remove and replace them to change lengths, and that takes an annoying amount of force and is easy to hurt yourself while doing so, and (b) they don't even fit on very well, somewhat unevenly - one end sticks up higher than the other end no matter how I attach it. Therefore the cut is likely at least somewhat uneven. I really wanted to love this Wahl, but I'm definitely going to exchange it for another brand. Maybe the Panasonic wet/dry easy-adjust model (Panasonic appliances have always impressed me, and the convenience sounds like a big win) or maybe even just get another Philips-Norelco cheapie. It worked much better than this, for years - at half the price.

      Upgraded trimmer model

      • Verified PurchaserVerified Purchase
      • My Best Buy® MemberMember

      Purchased at best buy for 59.99 at a $10 discount. Heads interchange easily. used daily x 1 month and still on initial charge. I question the longevity of the on/off switch - as it seems to be a "touch switch" and really does not depress much and "click" (seems to operate like a tv remote control button, but requires about 5 x the force to activate it) it comes with detachable: detailer, t-blade, rotary nose trimmer, and detail shaver I does not come with the Detchable dual shaver or trimmer head. I bought both from Wahl deliverd for $20.95. I was replaceing one of the older trimmers with the 3 AA batteries. The trimmer head compared the the older model is sharper, does not cut the skin, but seems to "catch" on the hairs at times. Have not tried it on a beard yet. more for trimming up what the electric razor may leave behind. the snap on beard length attachments seem cheap plastic - can't comment on their longevity. full charge in 1 hour with 4 hour run time. says if dead, one minute charge will give 3 minutes of run time 5 year warranty I would purchase this again.

      Facial hair gets caught, OUCH!


      So the thing looks sleek and I was impressed with the battery life; felt like I hardly charged it at all. BUT, my main use for this trimmer was for the beard. I only ever used the #1, #1 1/2 and #2 (honestly way too many attachments to unpack, but at least there were many options). Every time my facial hair would get caught in between the trimmer blade and the attachment and almost yanked out of my face. Very painful. I tried different attachments but they all had the same results. I just flat out could not get a full stroke through the beard with solid pressure against the skin without the hairs getting caught. My one hang-up on BestBuy is their return policy. I waited too long to try the trimmer out before the return expired, so my brother ended up with a new barely used one. Doubt he'll have a different result than I did, but maybe his threshold for pain is higher than mine. Would not recommend this trimmer.

      Not as good as expected


      I used this one time and am returning it. First of all, I had trouble shutting it off. I kept hitting the power button and it stayed running after numerous attempts. As far as the actual use of this, it probably does about everything else except what I needed it for. It is good for trimming the edges of a mustache or goattee. Trying to get the right length you want is a different story. I tried using the slightly longer guards to trim, and it did nothing but glide right over my hair. I used the next size down, and it took it down to around a stubble length. This product is absolutely worthless to me as far as maintaining my desired hair length. For $60 I was hoping it would be able to do everything I needed. I guess I will have to return it, and get a trimmer that has the spin knob in the middle to adjust the hair length by each millimeter, and buy a smaller battery powered trimmer for the detailed stuff. I think they should've forgot the haircut part of this item, and concentrated more on doing all facial hair.

      Great looking beginners trimmer

      I purchased this trimmer in March 15' w the intention of using it every once in a while, As I am a man w a difficulty of growing a thick beard. I loved the performance and I was even able to trim my hair between haircuts. The only complain is that it got a little moisture inside one day and it wouldn't shut off. I had to open it up and disconnect the battery and dry it off. Too many small plastic parts despite the outer stainless steel shell. This is something you won't experience with higher quality trimmers. After I put it back together some of the plastic parts were broken but nothing hat prevents use of the trimmer. I would give this trimmer a C+ but still would recommend it to someone who just going to use it occasionally but not often. Not bad price either and it's very nice slick trimmer

      I purchased this for travel purposes overseas because I couldn't plug my other shavers in. I wasn't sure about the battery operated shavers, but this thing is great! It cuts well, just as well as my plug-in shaver, and the battery lasts a long time. I use it to shave my head, and it does a great job. It doesn't get 'bic' close, so don't get that idea; I still go over my head with a foil shaver to get that nothing-there look without bic'ing. My only two complaints and they aren't big enough to take any stars away are that the power button is sometimes hard to push to turn on/off and the head pops off when trying to clean it in a certain direction. Other than those two things, I love this thing and have actually not used my plug-in shavers since.

      For bead trimming alone it's not so bad. My main complaint with this is trying to trim without a guard. I use an electric shaver for my neck as I have sensitive skin. If I go too long my stubble becomes to long for my foil shaver and need to trim down. I felt like when I would trim down stubble it would miss a lot of hairs and pull out a lot of hairs. I actually had the main head break on me about 3 weeks into use and could only use the longer 'T' head blade to do anymore cutting. As the beard guards only fit the smaller blade I could only use the larger guards reserved for hair cut buzzing. I feel like this trimmer does nothing special. At the price point, I would expect there to be something standout about it. It looks nice yes, but thats about it.

      Wahl 9818-800 review
      The Wahl 9818-800 is a sleek stainless-steel beard trimmer with a hefty price tag. It comes with all the bells and whistles, including four cutting heads, one of which can be used to trim nose and ear hair. Even so, you'll feel short-changed ifFull Review
