Review on 🧱 Camco Fasten XL 2x2 Leveling Block - Interlocking Design for Easily Stacking to Desired Height - Gray - 10 Pack (21026) - Includes Secure T-Handle Carrying System by Philip Wagner

Review update: Product was replaced as soon as I emailed the company. Many thanks for the quick response. I bought these leveling blocks in August 2019. I delivered them and put them in the trailer storage box. In June 2020 I finally did my first hike. Took the packaging off and was glad my pendant was lined up. I stacked the blocks as directed and pulled my trailer up to them. The blocks immediately crumbled. I have them 3 below, 2 in the middle, one on top. Please help! I read on the packaging that there is a guarantee. I hope it was just an accident.
