Thanks for your positive comments dear Rafaqat.

Please use our product correctly according to the instructions. Please do not blame our product quality for problems caused by your improper operation. For any product of this model, it is required to attract solid steel plate at least 55mm thick. However, you used it to lift a 15mm hollow steel plate. The steel plate is too thin, resulting in insufficient suction. This is not a product quality issue. Every product undergoes quality testing before leaving our factory, and only those that pass quality checks are shipped out.We have been exporting this product for over 10 years and it has always received high praise from our customers. We have never encountered a situation like yours before.Sincerely hope you can understand. Thank you very much!
