Product review (4 stars): I agree with prior review on many points as well; overall very happy
I purchased this dryer (along with the matching 300 vision series washer) two weeks ago at PC Richard's for $699 (free delivery) and am so far very happy.  It works well and like the previous reviewer, I don't use all the different settings (the later model series like the 500 and 800 have even more settings, like steam cleaning, wrinkle reduction which adds a few shots of steam to the dryer etc.)...I just want my clothes dried quickly and without scorching them.
And this machine does what it says.  I fill the dryer up about half full and the load dries in 30 minutes; clothes are nice and warm when they come out, not scorching hot, and they are dry but not wrinkled.

(Note to the previous reviewer (Davina), the 300 series dryer should let you turn off the annoying beeping alarm by depressing the two top buttons (the Econo-dry button and the other button right next to it) at the same time).

I have to agree with Davina that the lint screen is WAY too sensitive.  The beep went off twice the first time I used the dryer (I had it set at cotton/regular dry) and it stopped the dryer until I pulled out the lint screen to clean it (I admit, the first time it went off, there was lint in the screen, but it went off again 10 minutes later with no lint).  The folks at Bosch recommend that you don't use dryer sheets (which I wasn't) because the residue sometimes sticks to the sensor and that you makes sure the lint screen holder is free of dirt before you run the dryer.  I haven't used the dryer enough to see if my "cleaning" the lint screen holder (by blowing in it) fixed this problem or not, but I did about 5 loads and it lint alarm hadn't gone off again (granted, for the first load, I set the dryer on the dampness-sensor settings; for the last four loads I simply set it up to dry for 40 minutes and the lint alarm didn't go off.  That's fine for me.

So overall, I'm really happy with the dryer.  It dries quickly and efficiently (by the way, my old dryer was electric and it ATE electricity; I'm looking forward to getting my next ConEd bill to see how much money I'm saving on this gas dryer).
