Review on VIVOSUN Cordless Vent Blower Speed Adjuster 🌀 - Variable Speed Controller for Inline Duct Exhaust Fan by Molly Kaye

This device is very simple at heart (just a socket with a potentiometer attached) but it does the job well. The button is surprisingly smooth and pleasant to use (it feels like something you'd find on a high-end sound card or something). But overall I don't really like the design of this thing. It's very wide and tall, blocking all other exits around it. The orientation of the plug, handle and socket also means it's impossible to place them behind anything, as the cord exits the handle at a 90 degree angle, meaning one of them will always be hidden by the wall socket. If they redesigned the case to make it smaller and more thoughtful in button placement, I'd be a lot happier.
