First off, my Vevor purchases have been hit or miss. My experience has been that their products are rarely as advertised. That said, for the price, I was willing to chance this heater. I would say a solid hit on this buy. Everything worked as advertised and I am quite happy with this purchase. I would give it five stars but the fuel pump is very loud. If you intend to sleep with this heater inside, buy GOOD ear plugs. If you place it outside and duct in, realize the remote is useless. Nevertheless it heats awesome and uses surprisingly little fuel.
