I bought a set of 5 resistance bands from them, they were of shocking quality. You could see through 3 of them, and within a week of use two have snapped and one has split. They're also much smaller than the pictures suggest, and don't have the levels of resistance printed on them like in the pictures. I wrote a review on the Nuova Health site, but it hasn't been approved, let's see if it is or if they only display the favourable reviews!
