The Fitnus Knee Sleeve is a basic compression knee sleeve advertised as an all around solution for knee swelling, soreness, and stiffness.

The Fitnus brand markets a number of products in different categories, including various compression clothing, a smartwatch, and electronic scale, among others.

Below we take a closer look at the Fitnus Knee Sleeve to see if it's worth the price and if it lives up the the seller's claims

Choosing a Knee Brace

While buying a knee brace may not seem like a big deal, this purchase should actually be given a good deal of thought and planning.

There are many options on the market and many factors need to be considered, the most important being the specific reason for needing a brace.

Typically, knee braces are used after an injury to one of the knee's major components, such as the ACL, MCL, patellar tendon, or other ligaments and cartilage. 

They can also be used to alleviate pain and complications for degenerative disorders such as Osteoarthritis.

This is why choosing a brace should be done while in the care of your doctor or physical therapist, because they can recommend an option that is specific to your needs.

Depending on the design a brace can have different functions.  There are 4 main types of knee braces:

Prophylactic Braces

These are commonly sold in sports stores and are widely available.  They come in several styles such as basic hinge, knee sleeve, or patellar tendon straps.  

The Fitnus Brace falls under this category.  They are used to protect the knee joint and prevent injury.


Rehabilitative Braces

Used mainly post surgery/injury and designed to allow the knee to heal.  They may limit motion and keep the knee in a position to promote healing while avoiding reinjury.


Functional Braces

Also used in conjunction with a knee rehab.  Generally prescribed by a doctor to help users safely ease back into some activity.


Unloader Braces

As the name suggests these braces are used to ease the load of an affected knee and help with pain management and function.


Additionally, it's also important to take into account how well the brace fits and how it feels when you’re actively using it, which may depend on personal preferences.

Fitnus Sleeve

There isn’t much information on the Fitnus website about the company or the product aside from some general claims.  

There are no details about who developed the product and whether they have any medical accreditations.

The company states that the product is made from a soft Neoprene material and has “state of the art stabilizing technology.”

The Fitnus Sleeve is one size fits all and comes in only two options based on gender.

Customer Reviews & Complaints

There are only a handful of websites that have reviews of the Fitnus Sleeve, and a majority of those are affiliate websites promoting the product for a commission.

You can find some actual customer feedback on the BBB if you search for the parent company.  

There they have a B+ rating and are accredited, however the customer score is 1/5, albeit from only 5 customer reviews.

Fitnus customer service reps do make an effort of closing complaints on that platform, which is a good sign.

On other review platforms the Fitnus Brace has mixed reviews.  Some customers have found relief from using the product and would recommend it, but there are also many complaints. 

One of the most common complaints is customers stating that they didn’t receive instructions with the product.  

Users had issues fitting and adjusting the brace and wished that it came with an instruction manual or a link to an explanatory video.

Other negative reviews mentioned that the Brace was too small and too tight.  Some customers also complained about the Velcro straps.

Note:  None of these products should be used in lieu of medical care.  If you suffered a knee injury or are experiencing pain or instability see a medical professional.


It can also help to have a medical professional recommend the type of knee brace needed prior to looking for one online. 

This can help narrow down your selection as there are many options and prices can range widely, from under $20 to $400+.

Is the Fitnus Knee Brace Worth It?

We would recommend buying a brace from a company that specializes in medical or rehabilitative care products.

These days virtually anyone can order a wholesale shipment of cheap medical products, rebrand them, and resell them directly to customers online.

While the company behind Fitnus Brace also markets a Fitnus Smartwatch they are not a health company and don’t have the most positive customer reviews.

It’s best to get the advice of your physical therapist or doctor on the type of support your knee requires, and then proceed to find a highly reviewed brand that fits those needs.

I WILL NEVER BUY FROM THIS COMPANY AGAIN.I HAVE BEEN WAITING ALMOST A WEEK and A half to get me money Back.They They haven't gotten back to me Nobody has contacted me.And they say 24 hour to get money back.

January 19, 2024

I read all the earlier comments. My right kneecap has been slightly sore for about 3 weeks. Now I wear two sleeves, seem to fit tight. No directions or size info. I called customer service and they quickly answered and young man was helpful. Said they will in 4-6 months come out with sized versions. I suggested putting a cord strap "ring" on top left and right to help older people pull them up. My only problem is my right leg must be smaller even though I am right-handed.

So, after 3-4 hours of working, walking right leg's sleeve slides down so donut hole that should be around the kneecap is low and center of knee is now aligned with the protruding top of the donut ring and that can make knee sore. Company is not a scam, but there are many out there including some that take you from FITNUS site to alternative site that is not them!

Not worth it!

I purchased this product as a gift for my husband. He wore it once and developed a sore behind his knee. He is diabetic and any sore is a cause for concern. He has already lost one leg, we don't need that to happen to the other. I wrote the company explaining the situation and asking for a refund. It is more than 10 days and have not heard back from the company. This is not what I call great customer service. I purchased this sleeve for $48. Now just a couple of weeks later it is selling for $24. The $48 was supposed to be half off. This is not truth in advertising.

Another piece of junk from CHINA,
June 29, 2023
I received the Fitnus Knee Brace, but it is too heavy and bulky, plus there are no instructions on how to to put it on! The velcro is very cheap or none at all. It is a piece of junk.

Where's my refund?
April 21, 2023

Ordered knee brace, was too small. Returned for larger brace. Received refund for first brace. Returned second brace still too small. never received money for second brace return. why? where? when?

The comfort and fit
April 19, 2023
I ordered it and it came a day before they said it was to come, which was a plus, but there were no instructions. Also, One size fits all do not fit larger leg or knee people. I contacted Customer service to return. They responded quickly. I tried to wear it and it was very uncomfortable.

First time buyer of any kind of knee brace
February 14, 2023

This company would get no stars because:

1) the deal was buy 2 get one free. I only received 2.

2) no instructions whatsoever. zero zip zilch nada. any company that swears by their physical/medical products would have comprehensive instructions one way or another. this company obviously could care less. i just received these so i’m searching the intranets for any type of instruction simply on how to put it on and use properly.

when i saw these advertised up in the corner of a different webpage i was on looking for god knows what, i thought i’d try them only because i’m a gimmick buyer. im also an electrician so i spend all day on my feet in various positions while working my craft. i’m 59 and i do have knee issues like the average man my age, so i wanted to try this and see if it helps or alleviates any of the uncomfortable motion i experience during my daily movements. for the price i paid, im going to give the product the benefit of the doubt for the time being and see how i feel about it in a week or so. i plan on wearing both braces all day especially at work. i hope i use them correctly!

i’m a great example of lessons learned the hard way: waste money first!

if i was a fiscally responsible person i would have reminded myself that the intranets are full of everything and many different types and at that point i should have contacted a professional for a consultation about my knees. that would have been the right thing to do.

don’t be like me. you should research first and still there is no guarantee that the company your dealing with has a policy that’s “human centric” and not “dollar centric”. good luck on that one!

Sleeve did nothing for me after wearing for 2 yrs. Is there anyone advertising that is not doing a con job on consumers? Show me one w/o publishing reviews that are bogus. Publishing independent reviews-not going to happen in our lifetime.

It works
January 24, 2023
This works. Fits tightly and relieves knee pain. Probably delays knee replacement surgery for 12 months

TO February 21, 2023

Just got mine. The material is scratchy and very uncomfortable. No way to know if I have them on right. The ONE video I found had a dude putting them on backwards!!! WTF. Take this off the internet please.

Getting a Refund
July 21, 2022

Brace too small, they said they were sending another brace. I never received it. I want my money back. Scam

Look for snother. Nothing special about these .
May 28, 2022

Too big, and too much material. Not able to get a decent fit. Feels like you got something wrapped around your leg that will definitely move and eventually fall down. T

here's zero instructions in the bag. I'll have to read thier claims again, if I can find it. But I remember something said about new age. I have a pair of these somewhere. They at least 10 years old, bought them ar a yard sale. I want my money back please.

I just received my Fitness sleeve, I thought I was ordering the brace because they did not ask for a size. I got the sleeve in a size XL it keeps falling off my knee. I have 2 braces and each one keeps falling off. Very disappointing. I have Not been able to reach via phone the customer service dept. I did send an e-mail explaining my situation and only received a message that they sell both the brace and the sleeves. I am still trying to send my purchase back but I don't have an order number. No paperwork online or in the bag with the sleeve. I don't have any high expectations about receiving my money back. I just lost $50.00 learning a hard lesson about buying off a website. This maybe a scam.
