The product I used last year was very dusty but the price was right. However, I paid for it in the long run with corrosion related issues with the engines on my equipment. I steered clear of XCU this year. It gave great color but everything stayed covered in dust. I've found a very clean 28-3-10 product with 5% FE and 50% Uflexx at a very reasonable price for this area. I'm loving the fact that I can run my machines for 5 days and have a 10th of the dust on them than I would have with them working one day using XCU. The lawns are looking great too. And the company has a nice little reward package based on year end total purchases. They try to encourage sales by offering reasonable prices and incentives instead of penalizing you by bending you over the counter because you've only come in a few times in the past few months.
