I purchased it in April it took 3 months with back log due to Covid19, it came from China. The packing was great no damage to the product. The instruction was vague and not detailed. If I wasn't a aircraft mechanic would have been horrific assembling. The construction is good, the heater is awesome. it took me a couple of hours to assemble by myself, its bulky and fragile with the glass door. I removed it from the box in the garage and took pieces in the house individually. Wiring simple 120vac 30amp breaker. I have used it several times no problems the temperature reached 175 degrees in an hour. its cooler from the knees down with vent hole in the floor and the ceiling I close them both for better heat. I really enjoy the product and would recommend to others.
