Great setup up. You get base handle (orange), metal roller ball that unscrews in middle and 2 inserts. Blue rubber ball with gel goes in freezer for 2 hours, orange ball goes in microwave for 45 seconds. Put hot or cold ball insert into metal ball and **** closed and attached to base handle.
you end up with a hot or cold therapy ball that rolls and you can massage in as deep or hard as you want with either heat or cold.
great product A++
****Update after one week of use****
The orange round heat ball is showing signs of blowing out-looks like an egg on one end now-pimple like bulge at top. Returning for a replacement. This may be due to over heating in microwave. Directions say 45seconds in microwave, but depending on power of microwave or what power setting its set to, might over heat the ball and cause it burst. after a week, heating it once a day for 45 seconds now is slightly leaking and looks like an egg. You have to be careful not to overheat it.
I read some of the other reviews, this is easiest thing to use. To remove metal ball. Grab Black base with one hand, hold tight, with other hand and turn orange top counter clock wise about a 1/16 of a turn and pull orange top ring off. Then remove metal ball and do the same thing. grab on end and turn counter clockwise with other hand. Its really easy.
5 stars for therapy use of hot and cold roller ball.
1 star for defective heat ball. Will see if it was just a fluke, defect one of or bad design. waiting on replacement to arrive.
*****Update*****
I emailed KT Tape support at: [****]
Told them what was going on with heat ball, they are sending out a new one at no charge, so they stand behind there product. Impressive customer support.
Gives an excellent, ergonomic massage, especially for trigger points and scar tissue. Comfortable even with major hand pain. Easy to carry and can't be mistaken for an adult device when in public. However, the steel ball is extremely difficult to open even for the able-bodied. It works without the hot or cold inserts, but the difficulty of opening it makes it very hard to get full value out. FSA-eligible.
There are so many similar products on the market, but chose the RT because of its unique features.
This one offers both hot and cold and it holds the heat and cold for plenty of time to use. It is able to do it because you heat and cool an insert rather than the metal ball. Most others have trouble with the metal ball rolling once it’s frozen, but the RT has no issues and rolls easily for both hot and cold massage. The metal ball and metal threads are very high quality. The design is very ergonomic and comfortable to use. The build quality is excellent and far exceeds the price paid. The black and orange piece was difficult to open out of the box, but once opened if you open and close it 6 times it breaks it in and than opens and closes smoothly. Using the unit without heat or cold also provides an amazing massage to every part of the body.
The design gets into the areas that an ice cube can not get. It really brings relief after a massage to the foot/ankle/calf.
