Query: Great potential, if it worked right

This sprinkler had great potential and worked great right when the water first comes on (for 5 seconds) and then the arms get stiff and stop whirling about. The arms are what my kids were most excited about, so it was quite a disappointment. We moved the sprinkler to different areas, different hose hook-ups and do not believe it is a problem with too much or not enough water pressure. Because the arms are made of a very thin rubber/plastic, we suspect that the problem MAY be that our water is too cold and the tubes are becoming rigid from the very cold water. Nonetheless, this sprinkler was a disappointment as the water did not spray all that far and the tubes pointed straight out to the side or down towards the ground. A regular oscillating lawn sprinkler (from lawn and garden section) would be more fun.
