Mathmos: Inventors of the Lava Lamp Adolygiadau

Thank you for your feedback. We are sorry to hear you have been disappointed with the performance of your lamp. Under the recommended conditions, Neo lamps have been tested to warm up within approximately 1 to 2 hours and maintain a consistent flow. New bottles can also require a short break in period during the first few uses. For the best performance, we recommend following the usage and room temperature guidance provided with the product. If you continue to experience concerns after further use, our Customer Service team will be happy to help.
