"Dear Sir/Madam Just wanted to say a very big thank you: 1. Your product works excellently and the solar panel is really effective even in 'not so bright' sunshine.(Had a solar power fountain once that only worked in strong sunshine and cut if I walked in front of it!) 2. My fish love the bubbles and glad they will be happier and healthier. 3. Delivery was very prompt and well packaged. 4. And your price was a load better than our local Nottcutts and other online suppliers. I would recommend you to anyone. Thanks again. - V Ward" -->
