This was a well packaged item that arrived in reasonable time once ordered. I opted for the simple rotary dial version of these heaters which is limited in functionality but I understood this when purchasing it. Set up was straight forward. I used a PC power supply to run it which handles the initial current draw well. When turning the dial only the first 6 LEDs lit up. I thought this might be a fault but Vevor came back to me to say that this was normal operation. Since then the heater as operated well and supplies plenty of heat to my small workshop. I intend on upgrading with an aftermarket controller, silent pump, and mounting outside.
