I have tried many different brands and types of exercise tubes. This is one of the best and also happens to be the least expensive -- the only brand I buy now. The "very heavy" rating is accurate as it is heavier than many of the exercise tubes available in stores. (However some online specialty fitness stores offer tubes with even heavier resistance but at almost double the price.) I like the fact that the handle rotates. Some of the more expensive and fancy solid plastic handles do not rotate which makes bicep curls, rotator cuff exercises, etc., awkward.
