                      Poor build quality
                      I picked this up to be a filter fan, the build quality is very poor. The back panel is so offset you can fit the feat

                        Poorly constructed
                        Right out of the box the plastic cover doesn't line up with the steel casing. This also makes the power cord notch and notches for the feet out of place. Additionally the metal cut out is too thin for one of the feet to slide into. Fan is louder than expected and wobbles. Paid extra for the Power Plus Steel Body version and not impressed.

                          Three separate quality issues
                          When I first pulled the fan out of the packaging, it was obvious that the housing was not assembled correctly. The grill on the front and back wasn't flush with most of the corners. The power cord entering the fan casing isn't lined up to a cut out that its meant to be fed thru and there are dollops of glue on the metal bars, but because the power cord isn't where it's designed to be, it's just hanging waiting to be caught by a spinning fan blade. The final quality issue I've found so far was a small chip on one of the fan blades. This is a big disappointment because I also have the much more expensive "Lasko Pro-Performance Pivoting Utility Fan", and it's a fantastic product.

                            lots of power but a bit loud
                            I'm using this fan to create a cube filter to remove pollen from the air. it is working really well and has no problem running for days without issue. I'm removing one star as the fan is fairly loud even on the lowest setting. my other lasko fans aren't quite as loud but aren't as fast. I think the addition of a 4th seeing would help add a bit more control to a fantastic fan. I highly recommend this product!

                              One out of Three Failed
                              One of the three fans we bought four years ago failed. Motor burned out on it. The other two are still going for now. So, I had an old lasko box fan which I purchased about 15 years ago that the switch was jacked up. Tore out the motor and blades from that old one and made it fit in the new one. Rewired it to the good switch. Walla! Good fan now! BTW, the old fans are built better than the new ones. Of, course!

                                Have this fan for two years now, still operates great. Not loud like high velocity fans

                                  Yes.
                                  I made an air purifier using this fan and its box duct taped to some 20x20x1 air filters and BOY does this fan blow! And that's a compliment. Judy 3000 was inaugurated about two weeks ago and has done very well in absorbing the pollen and dust in my home. The fan has 3 settings and I've only been brave enough to use the first. the first setting is so powerful I can cool the hot side of my pillow with it. Setting two could probably blow my cat off his feet if he crosses in front of it. Setting 3 is forbidden knowledge. If I could improve anything it's that maybe there should be a 0.5 setting.. but honestly, I have never been happier, ever, in my life.

                                    So far so good. Fan is about two inches wider, definitely more powerful and seems not as noisy as the cheaper model. Most of the fan seems heavy duty except the switch seems a little cheap. Hopefully it will last

                                    I have been running this model fan for years. Well worth the money over the standard model Lasko fan. The CFM rating is almost 50% higher. Strong, powerful, weather resistant motor. Highly recommend. One note: If you're using as a window fan, recommend Not attaching the legs. They may tear up your screens. But if using on the floor, you'll probably need to use them because of how powerful it is.
