Product review (4 stars): Works fine as long as sensor gets right by dryer outlet
My father got this model a few months ago and it works fine for him once he got longer PVC tubing to put the sensor right at after the dryer outlet, he had problems with the vent booster sensor being confused by pressure decrease due to lint buildup on the dryer's lint screen during the first load of clothes after the last lint screen cleaning.

During his original install using the included length of PVC tubing, it worked fine until the dryer lint screen got a thin to moderate lint layer buildup on the first heavy fabric dryer load (towels).  So after he bought longer tubing at local hardware store and got the sensor right by the dryer outlet (maybe 25' of tubing instead of the included 6' or so), the dryer can now go through multiple loads between lint screen cleaning instead of just a partly into the first load.

So then when I bought this one for my house, I just jot the longer tubing from the local HW store and put the sensor right by the dryer outlet (13' of tubing in my case).  It is working perfectly for me to do multiple loads and get a medium+ buildup of lint between lint screen cleanings without the vent booster sensor getting confused and shutting the booster off.
