You can only provide feedback for 30 days after receiving a product. I purchased this product: LED Grow Light 5/10/15/18/27W Full Spectrum Plant Lamp Dual Three Head for Indoor Greenhouse Grow Tent Plants Grow Light Adapter from the CAIYUE Factory Store. At first the lights were great, but then after a few months, they stopped working. The seller refused to honour the warranty. While I have gotten good things from aliexpress, do not expect them to honour warranties. I have been working with aliexpress for 3 months to get the warranty honoured and nothing has come of it. I have no recourse. This seller will continue to have high ratings even though her product is faulty and her warranty is not true.
