美国采购需求：毛巾加热器，毛巾杆加热器，艺术散热器，毛巾散热器，P&Bhusri 毛巾加热器，毛巾杆加热器

I recently bought one of your heated towel racks from Amazon, but I had to return it because it was defective. The issue was with the digital display, where the light kept blinking continuously. I'm curious if this blinking is a normal feature or an indication of a problem with the unit. I'm considering repurchasing this model, but I want to ensure that the product functions properly. Could you please clarify if a continuously blinking light is standard for this model? Your assistance would be greatly appreciated, as I want to make an informed decision. Thanks!
