Review on 🔆 SURLED 12V DC LED RV Interior Lights Dimmer Switch - Waterproof IP65 Knob Dimmer for Camper, RVs, Boats, Autos, Trucks, Marine, and Strip Lighting by Terry Napoleon

Handle worked as advertised, reduced my lamp's light level. ref=ppx_yo_dt_b_asin_title_o04_s00?ie=UTF8&psc=1 The said lamp also whimpers/hums annoyingly at all settings below 100%. Maybe the lamp is to blame, if I try a different dimmer and get the same result I'll update. Update: no, tried a different dimmer and all is quiet. This device was the cause. Update 10/19/2021: I was contacted via email and offered a partial refund if I remove the negative review. "We are very sorry that you had problems with the quality of the product. If you don't mind, could you help me delete the comment? We will be very grateful to you for your help. To thank you for your help and understanding, we will refund you (15)". When I declined, they upped the offer and repeated the request to remove this negative review. "$20 is fine. However, the company requires that a refund is only allowed after the review is deleted. Stay away guys.
