"The standard roller I purchased from you is awesome. Over the past year and a half, it has completely changed my training game, and is a big reason why I'm the fittest I've been since 2008. I used another brand of roller for over 20 years, and there was so much give/play on it that I hated roller training -- it always made my neck sore, I'd routinely come unhooked when practicing sprints, it was hard on my chair welds, and generally made for an experience that I only endured when the weather was too poor to train outside. Purchasing your roller, which is rock solid and smooth, has made me actually enjoy roller training (truly!). I no longer have the associated neck pain, and I never worry about coming unhooked at 20+ mph. I love how heavy it is because it comes closer to simulating a road-like feel, and I get a better sense of my true speeds. Even through the summer months I have continued to use it two days per week because it has really helped me increase my speed, helped me improve my technique, and is just convenient on days when I've been super busy at work. So, I just wanted to say thanks to you all for making such a fantastic product. "
