This topic has come up several times and I have replied to each and I certainly don't mind repeating my positive comments again as we love having rubber mulch. We've had it down now for 3 years and have absolutely no complaints with it. It does not float, it does not smell regardless how it gets wet and have never found and critters nesting. We purchased our mocha brown rubber mulch at Brown's Distributors in Fruitland Park. We are BIG fans of rubber mulch
