We put ours into the pool last night. It worked fine, shot up about 4 feet and the color show was magnificent. The kids loved it. It was easy to assemble. I read all the ratings and followed the recommendation to use waterproof marine duct tape to cover the 4 D cell battery compartment. The person also recommended taping on a small flat river rock to the bottom. I used two small river rocks and you need to make sure you don’t cover up the air hole that sucks up the water for the fountain. It helps with balance and keeping it at the right water level. I am so impressed with the ratings and recommendations from Walmart Customers. I copied the instructions and have copied them into this. I took it right out after we were done and put it into a same place to dry out between uses. I also bought the $5 insurance. Maybe that was overkill but I really wanted it to work and it did! WATER PROOF BASE W/MARINER DUCT TAPE PRIOR 2 USING 06/14/2013 Since a lot of negative feedback was given…I decided to “water proof” this product PRIOR to putting in our pool. I used water proof “mariner quality” duct tape over the compartment where the water will enter. So far no water leaking into the battery compartment! NO RUST! When it’s time to change the batteries…I will take off the tape…put in the new batteries AND re-seal the battery compartment AGAIN. It’s not too much of a hassle. Additionally, to keep the product in the center of the pool I “added” a small “flat” stone, affixed with a small piece of the mariner duct tape, the flat river rock taped to the bottom of the product makes for a great anchor. You can also tape a med.-to-heavy weight “washer” to the bottom, I prefer the flat smooth river rock…then I don’t have worry about the “washer” becoming rusted. Be sure you REMOVE product from water when not in use. Dry thoroughly, if needed. The spray height reached approx. 4 Ft. at times…sometimes LESS-approx. 3 ft.- I don’t know why, when I figure it out…I’ll post again. BE SURE TO PLACE YOUR “WEIGHT” IN AN AREA THAT WILL NOT BLOCK THE SUCTION/FLOW ON THE BASE OF PRODUCT. If your product arrived “cracked” Walmart is always great about returns, damage products, defects from manufacturer. Just keep the receipt and explain to the Rep. at customer service what happened. I hope my suggestions help!
