Best foam roller I have found
936899
I am a doctor, therapist and yoga teacher and have used rollers of various sorts for many years.  Body rolling is an excellent method for pain relief and to increase endurance and performance in athletes.  What i especially like about this roller is the consistency of the foam.  It is firm without being too firm for comfort.  The hills and grooves on the device are excellent to get in deeper in various places, especially over boney prominences.  Much more efficient for back and leg rolling than a traditional roller.  And firmer than traditional therapists rollers as well.  I plan to order another one for my personal use and will use this one with my yoga therapy clients.  I doubt I will continue to use my traditional rollers now that I have found this one.  I received this product at a discount for my honest review but was already planning to purchase it anyway.  I could not be happier with the roller and will purchase again in the future.

I love this foam roller. I regret not ordering the longer one but I still like this one. I use it almost every day. Thank you.

We absolutely love our foam roller. It has so many different uses. We originally bought this so I could stretch my pecs by laying on it with the roller parallel to my spine. Hubby uses it to work kinks out of his back. He also had a flare up of bursitis and our chiropractor showed him how to use the roller to help alleviate that pain. This is a real winner at our house, even the kids use it!

This is a very firm, knobby roller which is great if you are used to using a foam roller and can tolerate a firm roller with this kind of strong texturing. I used it with some of the exercises from my physical therapist and found it worked great. What I like about it is that it is a lot less long than my other foam roller, which is 3 feet long. However, that does have its downsides, as there are certain exercises that need the 3 foot length, and also the 13 inch width is so slim that you have to position yourself absolutely perfectly to make sure it is supporting your body properly. I wear a size medium to large and clothing and found that this was just a little too short to be comfortable for me personally. However, if you live in a small house and really need a smaller, highly firm roller, this is a good option that looks like it will last for some time. I received a sample for review but the opinions are my own.

I have been foam rolling for years, and this one really gives me a buzz! The addition of three levels of vibration adds tremendously to the effectiveness, you can feel the muscle tension melting away.
When I'm ready for ibuprofen, and always try this roller first. It's an athlete's secret weapon!

This is my first foam roller and so far I love it!! I keep it at work (I'm a massage therapist) and it helps me get through my day and loosen up before I have to give a massage.  It's easy to use and is great if you can't get a massage or adjustment! So far it's held up great!

I have used two other kind of rollers in the past and this is the best. It is solid with just enough "give" to make it much to easier to stretch out on. Even my husband who was deeply skeptical now prefers mine to his own.  I started using because of lower back discomfort that wasn't so severe as to send me to a therapist. Stretching out on my blue cylinder cleared up that problem easily. I also find that I now have good range of motion in both my shoulders. My left had been much tighter than my right. My only quibble is this: I would have liked to have gotten a booklet with some suggested uses. I have never seen it used except by my husband who got specific directions from his physical therapist. Thanks

Best foam roller ever!! I love the 2-in-1 idea. The carrying case is great for travel. This has been great for rolling out stiff sore muscles.

Well worth owning! I've used other foam rollers. This one is more solid, strong, yet still soft. Does an AMAZING job on my muscles and also gives my back a nice crack adjustment. Helps me so much. Highly recommended!

This is the first foam roller I've ever owned, so it'd difficult to compare it to other rollers. However, this one has been great! I use it several times per week on all parts of my body - the size is perfect for almost all stretches / exercises. The only stretch that I can't do with this is lying on it face-up long-wise (like a spine stretch) - a longer roller would be more comfortable. That being said, this size roller does everything that I need it to do, and is really good quality.

The best foam roller ever!! Better than advertised -- helps work out the knots and soreness. Would recommend as a "gotta have"

This foam roller is highly dense but exactly what I needed. This works great for pre/post workout rolling and the 6x18 is larger enough to use for two legs at once if needed. The product does not indent easily, meaning it should last a lot longer, even with the lower price.

This is exactly what I wanted in a foam roller and the price was right!

I've been foam rolling for several years and have tested many different types of rollers. The Rumble Roller is the first roller that I felt gave me an excellent deep tissue massage on my back, butt, and legs. The teeth really dig into to muscle and provide great myofascial release. After several hours on a road bike, this roller is best alternative I have found to paying for a sports massage. However, it is harder to use on some areas. I like to roll under my arm pit and along the side of my torso to get my latissimus dorsi and external obliques. The teeth are a bit extreme for these areas so I have to support some of my body weight to take off a bit of the pressure, which is no big deal. Although, most often, I just use a traditional foam roller for these areas and the Rumble Roller for everywhere else.

I bought the travel size, which is rather small at 12 inches. If you are bigger than 5'5" then it might not stretch the length of your back and you will wish you bought the longer roller.

I feel like this roller is worth owning but is overpriced because there aren't any competitors. I remember when I bought my first traditional foam roller many years ago and paid about three times more than I would now that many companies make rollers. I imagine the price will some day drop on the Rumble Roller too.

I also think the Rumble Roller needs to improve its design. The inside core should not be made of foam. Instead it should use hard PVC so that it will last longer. Many of the new designs for traditional foam rollers use a hard plastic for the core, and it makes a big difference. Rollers with hard plastic don't start to sag in the middle over time. I hope I won't have to replace my Rumble Roller in a couple years as the foam packs down.

I am a licensed massage therapist.  I specialize in deep tissue massage.  I have used, benefitted, and recommended foam roller therapy for over 7 years.  I love this product.  I prefer the black axis foam roller from OPTP.com for home use because of theit size.  But this product is nice and firm and is great for travel.  I have several clients who travel regularly, and the larger rollers just aren't very convenient for packing or carry-on.  I have a client who had her roller confiscated.  The beauty of this roller is that it can pack into your suitcase and you can stow clothes inside of it, so it takes up very little room in your luggage.  Plus it is much firmer than most other rollers on the market.  It is well worth the price.

I train a martial art, so I wanted a smaller foam roller I could keep in my gym bag for before and after class. This one is great. It's short enough and small enough diameter to fit in any gym bag, but it is still plenty big for any foam rolling needs you have. It's really nice and firm due to the hard plastic interior tube. The padding on the outside is of moderate firmness. No complaints there. All in all, this is a really nice foam roller for all-around use and it's perfect as a travel sized roller to throw in the gym bag. Seems sturdy and well made, so I anticipate getting use out of this for years. I love the plastic tube in the middle that will ensure this roller keeps its firmness. The all foam ones tend to break down and get soft relatively quickly, which makes them not effective.
