Thanks for posting that Ron! I'm due for some new magnets and those look like they deserve a trial. I have never had a problem with drip loc, but that video looked like it was meant specifically against them. Don't get me wrong! Drip Loc is great! I love their magnets, their hinge kits, and their duct and fan access panels! But, Omni has my attention!
I like omni's Hinge! I have installed quite a few of them over the last year or so and all went on without any issues.. Very pleased with that product!
They are the best for side mount fans that we have found. If you get a look at one they are really well made with high density nylon bushings on the hinges and strong base plates for both the fan and base that spread the load over a big area. In all honesty we end up doubling the duct lips since they become the weak part of the mount not the hinge and have trouble supporting the weight when the fan is open.
