I received a 2 gallon kit as part of a 4 gallons replacement as the shipping company lost one of two boxes from my order. I contacted customer service and within an hour I had an answer and things were settled. Customer service deserves a 10/10. They were friendly, had a super fast response time, and fixed my issues without complaint or any hoops to jump through. I love this company and the quality/price value on the resin. And replanting trees?! Yes please!
