Product review (4 stars): Good, not great
We purchased the Acme Miami Dryerjet to help resolve a long-standing problem with a very long dryer vent run, probably about 30 feet with 3 90-degree turns. Overall, it appears to be helping and reducing drying times but not as dramatically as some of the reviews we read before purchasing the product. I'd say that the installation instructions leave a little bit to be desired, for example, figuring out which side to attach the vent pressure hose to (the hose that goes into your dryer vent that determines when the unit turns off and on). So if you're not mechanically-inclined or have the willingness to do a bit of trial and error with the settings, don't try installing this unit yourself. Having said that, the stand-alone design is about as simple to install as you're going to find -- and I looked at a number of different alternatives. And once we figured out the right way to install the pressure probe into the dryer vent and got everything adjusted, it works as advertised -- the booster fan turns on when the dryer is turned on, and shuts off once the dryer goes off. It's fairly quiet, too. I'd say on the average load of laundry, it has reduced drying times by maybe 10-15 minutes. We've only had it installed for a couple of weeks now, so I can't speak to the longevity of the unit. In addition to the convenience of shorter drying times, I'm hoping that the savings in the amount of time we have to run the drying will help pay for the cost of the dryer vent booster over time.
