Beware of Silicon Solar's exchange/return policy! This item was recommended to me by their sales rep, and it is the most underwhelming water pump I have ever seen in all my professional years. The pump is TINY and weak, the LED lights are dim and don't illuminate anything, and the fountain heads are of very poor quality. The solar panel doesn't come with any mounting bracket, and if one were to mount the panel to something themselves, it would void the warranty. After placing the pump in a clean, freshly-filled pre-fab pond, the pump worked for one weekend, and then began to fail over the course of 2 more days. After calling their customer service reps for help in exchanging it for something of better quality (like their lighting), I was reminded that I would need to pay a 25% RESTOCKING FEE, as well as shipping, which is approximately $15 from Seattle. So after the exchange, I would only get $60 of store credit. Quite a racket they've got going. They should add this to their return policy: "This item loses 40% of its value after purchase." That way, I wouldn't have bothered.
