Great fan

The fan is very good, but the speed-control has two major flaws. First, the three-pin connector to the fan does not fit well and if you apply a bit of pressure, the pins inside the connector bend easily, this is in my view due to poor engineering. I found several reviewers of the Hyper Fan that complained about the same problem with the connection of the speed-controller and the pins bending.The second major flaw of the speed-controller is that in the lowest setting, the fan does not stop, and it continues to operate at 35% of it power, this inability to turn the power to zero would be okay if the power-controller had an "On and Off" switch, but the speed-controller is lacking that necessary switch to turn the fan completely off.For customers like me, who buy these fans to use as generators of air-flow and static-pressure in order to drive an air filter system in my Clean-room, that I use exclusively for health reasons, the lack of a switch in the dimer to turn off the fan from a distance is a Major engineering flaw.Even some of the cheap after-market controllers sold on Amazon, include the "On and Off" switch, it is inconceivable that a fan of this quality, that sells for double the price of other fans, does not include a simple and inexpensive switch in the speed-controller.It is a great mistake, for the manufacturer of these great fans to "assume" that every potential buyer of their products will be interested only in growing something, and therefore never have to turn off the fans n the future. The distributor of these high-quality devises is narrowing its market-share unnecessarily by erroneously assuming that growing will be the only intended use.Hyper-Fan, please read this and do something about it, you are seriously compromising the usefulness of your products due to something that could easily be added to your devices, without significantly impacting your production cost.Yes, sure I can go out and buy my own external power-switch, but when comparable fans sell for half the price of these fans, I refuse to add another $24 dollars to my order to turn a fan that cost twice as much into a useful fan for my intended purpose. Please Hyper-Fan!!! for your own good, pay attention to this!!!
