you can check if the screws on the blade brackets attached both on the motor housing and the blades are tightened and check the blade are the same distance from the ceiling to the blade.If it still wobbles,use a blade balancing kit.
There’s a ceiling fan sold on Argos that looks identical to this one, except they renamed the model to “home Boston” and it has clearer light shades. I’m planning to get one for my bedroom, but it’s sold for £80.00 which is quite expensive in my opinion.
