I had used my original thigh master that I purchased in the 1990's almost daily and it finally broke so needed a replacement. This one works great. It helps keep my thigh muscles toned which in turn helps my knees.
I find I use this roller more than the other. My physical therapist suggested I buy a roller for home use. I use it after I get home from work on my legs. I love it and highly recommend it. I bought two rollers. One that has grooved rollers and this pointed roller.
Also when it comes to it being waterproof I spilled water on it and it just ran down. It was not bulky and she had room for layering. I got this coat for my 12 year old daughter and she loved it. ???? I would recommend. We spend an entire day skiing, the temp was 20 degree in the morning and in the night of course it went down. But throughout the whole day she didn't feel cold even after it started getting windy she was still feeling good.
AMAZING QUALITY for the price. I gave it to my husband as a gift and he wore it every day this winter.
VERY warm jacket. He sometimes says it gets TOO hot in there, he has learned to wear less layers with it. my husband loves it.
