Product review (3 stars): OK design, couple of quality control problems.
UPDATE 2016-05: A full year on, and it is still functioning well. The only strange thing that has come up is this thing seems to have unlocked 2 additional speeds. Although there are only really 3 speeds, the 5th and 6th speeds don't do anything. It uses what looks like an ATMega chip for all of the functions. Sometimes it does not register button presses which is strange. I've upgraded from 3 start to 4 star as it is used almost daily and moves tons of air. The filters are washed monthly in a dishwasher and they have held up so far. If the front panel dies I'll update the review again with that information. If it does die, I may just get a piece of black plastic and add attractive switches to it as we don't use the clock or timer functions.
ORIGINAL 2015 Review:
First impressions is this is a china made product with out much quality control. First issue I noticed was the fans were not centered in their housing. They seem to be attached with rubber grommets and I'm not sure if shipping caused these to be moved or if they came that way. The unit shook quite a bit until I straightened these out. The second issue was after the first use the unit would not turn on and the display was blank. I opened up the unit and jiggled some wires and it came back on. On the main power supply/relay board the front panel plugs into the connector was lose. It seems that the board and front panel units were manufactured at different locations with variable quality connectors. The fix was to use some silicone adhesive, the same type the manufacturer used on all the other connections EXCEPT this one. That fixed the issue with the device failing when that connector became lose. As far as sound and air movement the design is quite good. At full speed it moves quite a bit of air with not too much noise. The grease filters seem decent as well as the overall quality of the metal working. After fixing the couple of manufacturing quality control issues, this seems like a good bargain. Other units similar to this one were easily several hundred to a thousand dollars more.
