I can speak from first hand experience regarding
Secret Jarden Oscillating tent pole fans ... They are junk! The ones I bought didn't last one grow before the gear in the oscillating mechanism wore to the point it wouldn't oscillate anymore. I bought 4. Some lasted longer than others, but none lasted like they should.
On the other hand, I've had great luck with
AC Infinity products. I'll likely order a few at some point of time in the future. I just upgraded my airflow in the greenhouse with a pair of 16" oscillating industrial wall fans so it will have to wait. Hopefully this fall I can get them for my next indoor run.
That's what I was reading and I really don't care for buying that stuff just to dump it.
I have three
ac infinity 4" inline fans, (2 of the fans) going for years now and they sound as good as day one, nearly no sound with muffler on one end and filter on the other, still plenty of airflow on low settings. Got a different inline 4" recently that was not cheap either, had to return it from the noise and get the 3rd
ac infinity.
Really hope to be as happy with this oscillating fan, pretty sure I will be and the plants will love it coming from a 4" 10 year old, non oscillating, brinkman windy trying it's best to provide for a 4x8 tent, hahaha, not happening. Think this would not be suggested to be alone for a 4x8 either, but if I keep they humidity and temps down, maybe it will be enough.
I just got a tower fan for $100 (New/used from amazon so I didn't actually pay that much). Thing didn't even make it out of the box before trash, turn it on, thing would make noise and get worse till the thing stopped running, probably saving up energy to start a fire or something. Trash, Dero was the brand of the tower fan, I don't suggest them.
