I've seen the ads for the turbo grate, and although the benefits sound nice, I just can't wrap my head around how the thing looks or works. I don't have any fan control device, and don't really see the need for one for me at this point. Do many of you have and/or recommend the turbo grate? Or should I just wait and get a Digi Q when the time is right? Would one have / use both? Thanks in advance for any insight!
