Review: Fire Hazard - poor product - Bought the transformer for my elderly parents to use on their Eufy doorbell. The device exploded when plugging into the power socket mains. It literally separated from the casing and tripped the power in their property. My parents were shaken up! The device also does not fit UK sockets so needed to buy an adaptor at some expense. This is not the first review I have read on this item being a hazard. desertcart, do a thorough review of this product before you sell such things on your platform.
Review: Eufy hard wired transformer - Bought this last November 2023 wasn't cheap you have to use a 2 bin adapter to plug it in to a uk socket just decided to use it today straight forward to wire plugged in powered up for seconds and then started to smoke, do not buy fire hazard desertcart should not be selling these things if there not tested and don't me uk standards.
