Probably the best body trimmer I've purchased. Replaced my one blade with this trimmer because it cuts better with no irritation or nicks.👍🙏

Compact, Quiet, and Convenient Groomer

This has been a really great body trimmer and groomer. I like that it’s not too big, so it fits easily into all the smaller areas I need it for without feeling bulky or awkward to handle. The size makes it easy to control and much more comfortable to use compared to larger trimmers I’ve tried before.Another big plus is how quiet it is. It gets the job done without being overly loud, which I definitely appreciate. The waterproof feature is also a huge bonus because it makes cleanup simple and lets me use it in the shower when needed.Overall, it’s a practical and easy-to-use groomer that does exactly what I need. The combination of compact size, low noise, and waterproof design makes it really convenient for regular use. I’m very happy with how well it works and would recommend it to anyone looking for something simple and reliable.

Clean & Precise Lines

This trimmer delivers clean, precise lines and performs exactly as expected for detailed grooming. The skin-safe blade system works well, making it comfortable to use without irritation, even on sensitive areas. I like that it’s waterproof, so it’s easy to use wet or dry and simple to clean afterward. The USB-C fast charging is a big plus, and the long runtime means it doesn’t need frequent charging. It's easy to use & seems quite durable. It feels well-made, easy to handle, and gives consistent results. Overall, it’s a reliable body groomer for anyone looking for neat, controlled trimming and smooth, clean finishes.

Packs a punch!

I’ve tried similar razors and this one might just be the most powerful I’ve tried! At 6800rpm, this thing is pretty strong! The form factor is pretty good! I’m not sure I’m sold on the color but I appreciate that it doesn’t look cheap. I’ve known supreme to put out some pretty solid tools in the barbering realm and I’m glad to see they keep that same energy here. The guards are a nice add on and USB-C charging make for a pretty solid wid!

Great Groomer!

Ordered on Dec 9 and received Dec 11. Shipping was fast and efficient. For the price of $29.99, this trimmer delivers excellent value. It comes with a storage bag, USB-C charger, and three guards, which makes it easy to keep everything organized.The system works well and feels safe against the skin with no irritation. It is waterproof, so you can use it wet or dry, and the 90-minute runtime on a full charge is more than enough for multiple grooming sessions. The USB-C fast charging is convenient, and replacement heads are available, which adds to its longevity.Durability feels solid for a budget trimmer. The body is sturdy and the guards, while lightweight, do their job. Functionality is straightforward and intuitive, and the fit in hand is comfortable, making it easy to maneuver for detailed grooming.Pros:✔ Skin-safe blades for worry-free trimming✔ Waterproof for wet and dry use✔ USB-C fast charging with 90-minute runtime✔ Comes with bag and guards✔ Good durability and ergonomic fitCons:✖ Guards could be sturdier✖ No charging brick included, only the cableOverall, this is a reliable and well-designed grooming tool that feels premium for the price. Perfect for body grooming and detail work. Highly recommend if you want something functional and durable without spending a lot.

Excellent shaver!

The media could not be loaded.









I’m very familiar with this brand and so far they have not disappointed me. I’ve ordered many clippers from them, but I had no idea that they had a personal shaver. This thing works very well. It doesn’t shave your hair down completely but it taking the majority or it off. This is great for a man or woman. If this is used as a shaver for the face it will take a man’s beard down to the lowest point. This shaver is durable and easy to use. It doesn’t have an indicator on it to tell you how much battery you have left on it. However; you do get a handy charger included to keep you a nice charge. This sleek design is perfect for wet or dry shaving. This is also nice for travel. The price is good in my opinion, especially because of the brand and high quality products that they sell.

Very nice shaver

I'm pretty happy with this little shaver. It gives a good close shave and doesn't cut the skin. The quality of the shave on the...intended sensitive areas...is very good. No cuts, so far. It also works great for a quick trim to facial hair. It's plenty strong enough to cut through a couple days of growth. The battery life is great, so far. It doesn't have an indicator of the percentage left, but I've been going on the initial charge for a couple of weeks now and it's still going. It has one button, so it's easy to use. It is also very quiet for having a strong motor.The design is pretty close to another one that I have from a different brand that was getting a bit dull. This one does have a nicer appearance, though, with the nice tan color. They're pretty similar in quality of materials and shave, but this one is a good bit cheaper, so it's a much better value.

Very powerful and nice looking trimmer

First off the presentation is amazing which would make it an amazing gift. It feels very dense and durable. Very seamless looking and comfortable to hold in your hand even when wet. The battery seems to be holding up amazingly so far I haven't had to recharge it after multiple uses so that's great too. Comes with multiple trimmer guards in different sizes, a charge cord, and even a carrying bag to keep everything nicely inside for easy storage or travel. Overall this is an amazing trimmer so far and I would definitely recommend this product or get it for someone who doesent have one already.

USB Rechargeable, very convenient

I like that the trimmer uses a skin safe blade that glides gently across sensitive areas with minimal irritation or pulling. I have used it in the shower, the waterproof build makes for cleaning easy. USB-C charging is convenient, and the battery has a good long runtime per charge

Great tool: Designed for Trimming, Not Shaving

After a couple of uses, I’ve found this trimmer to be a dependable part of my grooming routine. The battery life has been very convenient—I can get several sessions out of it before needing to recharge, and the USB-C charging makes powering it up quick and straightforward.In day-to-day use, it feels comfortable, very low noise & easy to control, with enough strength to handle thicker hair without catching or tugging. I’ve used it both dry and in the shower, and being able to rinse it clean under water makes maintenance simple.What I appreciate most is how gentle it is during use. I haven’t had to worry about irritation or small cuts, even on more sensitive areas, which gives a lot of peace of mind. It feels like a sturdy high-quality build & knowing that replacement-heads are available as well, also makes it feel like something built to last rather than a short-term purchase.It doesn’t give the super-smooth result you’d get from a traditional razor, but for safe, efficient trimming, it’s worked well for me.Comes in its own bag with trimmer heads, a USB-C charging cable and a brush for cleaning (dry). When charging, it doesn’t have a light to let you know when charging is complete (by red or green lights).Overall, It’s a great value for money and time both!

Excellent build quality , works great!

The Supreme Trimmer Testii is an excellent grooming tool that truly lives up to its name. Its skin-safe blade makes it perfect for sensitive areas like the groin, body, and bikini, providing a smooth and irritation-free trimming experience. The build quality is very impressive — solid and durable, it feels like a premium product in hand. What I appreciate most is how efficiently it gets the job done with ease, saving time and effort during grooming sessions. Additionally, the positive charge connection and short recharge times mean it’s always ready to go when you need it. Overall, the Supreme Trimmer Testii is a reliable, high-quality trimmer that I would highly recommend for anyone looking for a safe and effective grooming solution.

Being able to shave back and forth, not just forward, is a game changer

This trimmer has excellent build quality and feels ergonomically designed. The double blade makes finding the best angle much easier compared to other trimmers. The blade feels the most comfortable on my skin and is easily comparable to other sensitive trimmer options like Manscape, and I prefer this trimmer over that brand. Being able to shave back and forth, not just forward, is a game changer. I highly recommend this trimmer.
