I purchased a Keter Shed from Costco Online. Within 2 months the lid began to warp, and got gradually worse. I contacted Keter to request a replacement lid. Dealing with Keter Customer Support was the worst experience I’ve had with a company. Over the next three months of no follow-up, failure to meet commitments, lies, supposed escalation to management, nothing happened. They offered me a refund in writing and never came through. This company is the worst. I finally disassembled the shed and returned it to Costco, where my purchase price was promptly refunded. A+ for Costco and F- for Keter.
