Unlimited LIFETIME WARRANTY!
*Thank you for your patience as we ship products during the busy Holiday season. If your product includes an 80 lb mold, your package will hit the mail January 2nd! All other orders will be mailed immediately.
We designed Rock Weights to be your longterm fitness solution. We spent a year testing our products and modifying the design to make sure it can withstand the test of time. We are so confident in our products that we are willing to offer a lifetime warranty.
How it works: Add this "product" to your cart and check out like normal. Your account will be automatically stored in our system after you complete the order. This warranty will protect ALL PRODUCTS purchased during this specific order. If a product fails at any point down the road, you qualify to get your unit replaced immediately. It's that simple!
Please note: There is a difference between a product failing and user error. Examples of product failures: broken handle, cracked plastic, warping of plastic, etc. This warranty does not cover any errors made while filling the mold. We realize their can be a learning curve when filling your mold and that is why we created an easy to follow video tutorial to help you along the way: https://rockweights.com/pages/tutorial
Do I need experience with Concrete?
Absolutely not. Concrete mix is as simple as Pancake mix. Simply add water, mix, and fill the mold!
