Each product in the Advantage Line of Koi Pond Equipment was designed, tested, and built exclusively by Sacramento Koi to fill a particular need in the koi pond industry. Because we are the only major manufacturer of koi pond equipment that also builds ponds, we are in a unique position of being able to thoroughly test and refine our products well in advance of selling them. For that reason we have been able to develop a line of koi pond products that we are so confident will outperform the competition that we offer a “One Year, Unconditional Satisfaction Guarantee” on all Advantage Products. This means that for one year from the original purchase date of any Advantage Product, we guarantee you will love the product or we will buy it back with no questions asked. No other company in the koi industry offers such a guarantee. There’s a reason why we do however, and they don’t.
