For desk jockeys like me, the Cubii is a smart device that makes smart sense. It lets you burn calories without burning through your free time.

I've had my Cubii for 5 months, I'm a very heavy user, working four, ten hour work days a week, I've gone from burning 500 calories a day to 1500. With as much use as I've put it through, about 387 hours and 600 miles traveled on it currently, which I imagine is much higher than expectation, the machine has held up very well..."

"I have had one total knee replacement and another scheduled...Getting up is so much easier now and I feel like I'm doing myself some good by moving my lower body throughout the day."

I purchased my Cubii through their direct site several weeks ago and I could not be happier. Everyone at work is talking about it and trying it out. Such a great investment in personal fitness equipment!

"My knees are bad and I spend a lot of my time in a wheelchair after a stroke. This is super easy to do from a wheelchair."

"I can't believe how easy this machine is to use... When I use it, a half hour will go by with total ease, I can really feel my ankles and knees moving. It relieves swelling in my knees."

"Hi! I love my Cubii! It’s the best home exercise machine I’ve ever used. It’s perfect for using at the office if you’ve got a sit down desk job, and also great for using at home while you sit and play video games at your PC or on your couch."

"I love this! It's very sturdy and well made! I use it all the time! I'm using it now as I'm writing this! Customer Service is second to none! They are very helpful and friendly! One of the pedals was cracked so we called them and they were very apologetic and understanding! They shipped out another one quickly! I would definitely recommend this to anyone! I bought it for under my desk at work but I don't want to give it up at home!! I love it so much I'm going to get another one for work! You won't be sorry if you buy this Cubii Jr!!"

"I am disabled and can hardly walk at this time. I found this machine to be so easy to use so I could get a little exercise in. You don’t even realize your using it, it’s fun simple and great for everybody."

"I found this easy to use and it is not hard on my knees."

I'm a runner so already get a good amount of exercise, but love being able to get a little more during office hours. Using the Cubii has also improved my work posture because it's easiest to use when you engage your abs to sit up straight. The Cubii was easy to set up and operates silently which is essential in my open workspace.

Though it's great in my home office, it's even better to have at work - mainly because I spend more time there but also because of how well it fits under my desk. It's also quiet, which allows you to pedal away without disturbing your coworkers.

"I use my Cubii Jr. every day at work! It keeps me MOVING versus sitting all day. The machine is quiet and the quality has been outstanding. I feel so much better during the day (energy levels up, less soreness and stiffness). I did let the creator know (via email) that for future generation models - a larger out-put screen and that it be illuminated (as many people use this UNDER a desk) be added. The Cubii Jr. is one of my favorite QVC purchases."

The elliptical is much more ergonomic than other under-desk peddlers or bikes making for a more comfortable “ride”, and it’s super quiet so your coworkers will never know you’re exercising. The motion feels exactly like your typical elliptical – very smooth, and easy on the knee joints.

"I received this Cubii as a Xmas gift, and I love it so much! It's too cold to take walks right now, and this is a great alternative. Convenient, silent, and it works! I use it while watching TV and after a minute or two, it becomes automatic and I don't even have to think about it. Before I know it, I've gotten 30-60 minutes in! The motion is also gentle enough that I can read a book while using it. Thanks Cubii!!"

"This item is well made. Very heavy (you need that so it will stay in place). I had two kneed replacements and can't get out and walk so this gives me the method to exercise my leg muscles."

"I need a double knee replacement, and just had a gallbladder, cyst, and, a hernia operation. Needless to say it became very hard for exercise. This is GREAT."
