So my heater just arrived today.
THE GOOD:
It is currently running and being used to heat a work room I have back in my garage. It takes a few minutes to heat up as expected, but is doing a decent job and is actually very quiet. Actually I find the loudest part of operation to be a click sound from the fuel pump each time it pushes fuel. It isn't loud but because it is a repeated sound, I do notice it if there is no music playing or other sounds. I normally have music or something playing back there so that isn't an issue.
THE BAD:
Take the cover off your heater when it arrives and inspect yours when it arrives! I am glad I did with mine because I immediately found several issues.
It looks like after the (green) fuel line was attached to the tank, the line was pulled down tight so it could be attached to the lower heater part. There is plenty of fuel line but because it was pulled down like that and stayed that way for who knows how long - there was a permanent kink in the fuel line on my heater. I had to go to a local hardware store to get new tubing.
The power / control lines that run into the heater component rest against the outer cover. If you look closely you can see that just from the vibration of shipping etc. it had already worn through the outer most sleeve of insulation. Not an immediate issue but I did wrap this in some high quality electrical tape just to make sure the main insulation on the red wire (normally denotes POWER line) didn't get rubbed through.
Not shown but there is a square cut-out in the metal between the top (where fuel, fuel pump, display is) and the bottom half where the heater proper is located. The fuel line and that power line, both shown in the other pictures, run through that hole. The edges of that square hold / punch out were SHARP. Let me put it this way, those edges are sharp enough that when I rubbed my finger across them I cut my finger (not badly but still). I ended up taking some aquarium air hose, split it down the center, and put it on the edges so I won't have to worry about the fuel or power lines vibrating against it and ending up shorting or causing a fuel leak.
So in the end I am giving a 5 on value and ease of use (in general). Features is only 4 stars but then again, I did get the basic version. Quality is only a 3 and that isn't so much overall quality or how long I believe the unit will last but more about the issues I discovered and had to correct before first use.
