Accessories of Groomiist SST-786E trimmer.

2. Accessories come with it

This Groomiist SST-786E trimmer comes with 6 different combs to give you a variety of length settings. However, they are very limited. The accessories include the following things.

  • 2 stubble combs of 1mm and 2mm
  • 1 oil bottle and brush
  • Two beard combs of 3mm and 6mm
  • 2 hair combs of 9mm and 12mm

Like Phillips MG3720/13 all-in-one men trimmer, this Groomiist SST-786E device comes with no adjustable length bombs. The length settings in the combs are static. And, unlike Braun MGK3021 all-in-one trimmer, this device has no range. So, you have to stick with 1mm, 2mm, 3mm, 6mm, 9mm, and 12mm length settings. I don’t think there is nothing more disappointing than this.

One thing I don’t like in this grooming kit is only black colour combs. Groomiist should apply at least different colour to quickly identify the same of different lengths. Furthermore, it’s not easy to detach the head of this trimmer for blades wash. You have to unload the screws to get it detached, which is a little bit frustrating. As this trimmer has no support for the nose and ear haircut, Groomiist might have decided not to make the head detachable. This SST-786E device is not for all-in-one use.

The accessories don’t include the charger or the batteries. That’s because the cordless-use is not possible for this trimmer. This trimmer runs on direct electricity, which has its own advantages and drawbacks. The benefits are, you get a continuous performance, extremely smooth haircut, and full utilization of its potential. On the other hand, you will be unlucky, if, during shaving, the electricity goes.

Also, the cord that comes with this device is not detachable like its head. That’s I don’t like. One good thing is that the cord is 3 meters long, which is quite long for a free movement of trimmer during haircut or beard cut. Also, remember that the cord has a 3 pins plug. In addition to that, no need to worry about battery and its charging/discharging because it’s not coming with it. The corded-use trimmers like this Groomiist SST-786E are best for the barber to use all-the-day. Okay. Let’s head over to review its design.

3. Ergonomic design

This Groomiist SST-786E trimmer is designed for men. Its outer body is made of all-plastic. However, the plastic body is so durable to withstand the shock to the distance of 1-meter maximum. The front part has a white colour smooth finish whereas the sides and back have little bit rough black colour surface. The design of this trimmer is so ergonomic to hold for it a long time.

Ergonomic design of Groomiist SST-786E trimmer.

It isn’t following a single shape throughout the body. The top part is wider compared to the bottom part. Also, both sides have one notch where the sides are becoming a little bit wider. If you look at it further, the location of both notches isn’t the same. For the left side, it’s far from the bottom compared to the right side notch.

Furthermore, you won’t get frustrated even if you hold this trimmer for more than an hour. In my opinion, this trimmer is the most ideal for barber as it runs only on direct power. As all surfaces are not plain, you don’t have to hold it tightly to prevent it from slipping from your hand. In addition to that, the body of this trimmer is made of plastic. So, it absorbs almost all heat emitted by the electric motor placed inside the device. It doesn’t let you feel the heat, thanks to the double-layer. So, this is the best trimmer for men for a long time use in a day.

4. Haircut experience

This trimmer comes with 6 different accessories. Despite that, it doesn’t open all the ways for possible use. You can use this Groomiist trimmer only for your hair and beard. No use for the nose and ear haircut is possible. First, I’ll explain my experience on beard cut, followed by a haircut. Before I start, I would like to tell you that this device comes with Japanese stainless steel blades. The 440C SS is used to make the blades.

According to Azom, 440C grade stainless steel is a high carbon martensitic. It has high strength, moderate corrosion resistance, and good hardness and wears resistance. In addition to that, the blades are self-sharpening which tell you that they will remain as sharp after 3+ years as they were on the first time of use. And, more importantly, the blades have rounded tips to make smooth contact with your skin. Also, they are hypo-allergenic to the skin, which ensures no irritation after the haircut or a beard cut.

Beard trimmer experience

As this trimmer comes with 6 combs, it gives little more options to choose the length. For a stubble cut, you can go with 1mm or 2mm combs. For a short beard cut, choose 3mm or 6mm comb. Lastly, for a haircut or long beard cut, you’re left with either 9mm or 12mm length combs. The 12mm length settings maxed in this Groomiist SST-786E head and beard trimmer. It doesn’t matter which trimmer you buy, after the beard or haircut, your face gonna look almost the same provided that you’ve used the same length setting in a new trimmer. So, in my dedicated article on the trimmer buying guide, I’ve shown images of beard and head haircuts using different combs.

While beard cut, I found this trimmer average noisy. And, it runs on the direct power, it has given its full potential. During the complete beard trimming, I have not found it pulling my single hair. The beard cut went pretty smooth. The one thing lack in the trimmer is an integrated vacuum. Integrated vacuum basically gonna suck all the cut hair. So, you don’t have to clean the place. Indirectly it gonna save your time. Anyway, it has done the rest of the job pretty well. One important-thing I forget to mention here is that the blades don’t get noticeably heated during beard cut.

Haircut experience

As I said earlier, for the haircut, you can go with 9mm or 12mm length combs. You can also go with a 6mm comb, but the result won’t be satisfactory. During the haircut, I found it average noisy, which wasn’t annoying. As I’ve begun haircut just after the beard cut, I can say that the beard cut was silent. The haircut went completely smooth, not a single hair I found to be pulled-off. And, that’s the quality expected in every trimmer that undergoes for review at SimpleCare India.

During the haircut, I found the blades got heated a little bit, but thankfully haven’t crossed the temperature limit. The blades heating is also an important factor we consider before publishing the final ratings of the trimmer. If you need a trimmer in which the blades shouldn’t pick the heat, you must go with a ceramic blade device. As this trimmer doesn’t come with nose and ear trimmer, I have to head over to review its versatile use.

5. Versatility in use

Is this Groomiist SST-786E trimmer comes with a versatile use? The simple answer is NO. This trimmer has no integrated or removable battery. Its cord is not even detachable. This men trimmer can only run corded. And, the corded-use trimmer has many advantages. Also, many cons following it. The main benefit you get is a continuous powerful performance. In the cordless-use trimmers, I found the performance slowdown when the battery is near about to die. But, that’s not the case with this trimmer.

Furthermore, coded-use trimmer put a restriction on portable use and on the freedom of movement. If you’re a traveller, buying this device will be a little be regretting because you need to live electricity every time you use it. However, to offer good freedom of movement, Groomiist has equipped a 3 meters long cable. The cable is also soft and made of all-plastic. So, don’t worry, if the cable becomes wet due to water. However, it’s not recommended. Furthermore, the cable is so flexible that put little to no restrictions on the free movement of this SST-786E trimmer while beard or hair cut.

6. Final thoughts

This Groomiist SST-786E is a trimmer for men for head and beard hair. It only supports corded-use to deliver its full potential with a skin-friendly nature. The shape of the body is so ergonomic to hold, which allows a barber to use all-the-day. The one downside is the very few length settings combs coming with it. And, no one is adjustable. This device is not an all-in-one grooming machine as it has no nose and ear hair trimmer. The blades are carbon martensitic to give you the full hardness. To offer complete freedom of movement while haircut, Groomiist has kept the power cord 3 meters long, which is pretty awesome. The skin-friendly blades of this trimmer are made of Japanese steel. It is hypo-allergenic to the skin and has rounded tips that ensure smooth contact with your skin. All things are considered, I’ve rated this trimmer 4.2 out of 5 at SimpleCare India.
