This product is great!! I bought from this seller at Walmart three bars. Two are terrible to touch and scratched and have white strips from something that can't be wiped off, but this blue bar is good.
I got at Walmart RED, blue, and GREEN Theraband flex bars in the last few days.
The blue one is great: it's coated properly, so it's pleasant to touch and proper color. No white stripes, no scratches.
The red and green bars are unpleasant to touch, not coated, and have white strips of some kind of chemical on them which is impossible to wipe off.
