This is a softer lineup of foam rollers, as indicated by the light blue and pink coloring. It's a good way for beginners to get into self-myofascial release without inflicting too much pain on themselves. If you want to take it really slowly, you can get semi-circular roller, which is very stable.
If you're looking for a roller with enough pressure to help with muscle knots or tissue pain, this might not cut it in the long term. You might use it to get comfortable with self-myofascial release, but eventually a higher-density roller will be required.
You can get the 12-inch foam roller for under $9 and the largest 36-inch one goes for less than $20, all while a lot of alternatives cost easily twice that. For a budget-conscious buyer, this is a very attractive offer.

This is pretty much as hardcore as foam rollers get, and even if you've done foam rolling for a while it will provide a challenge. It's very high density, with large ridges that will give a very intensive deep tissue massage for getting rid of muscle knots and managing pain.

Depending on how experienced you are with self-myofascial release and how much pressure you want to put on yourself, you can get the appropriate option and then upgrade if necessary.
