Product review (4 stars): The little dryer that could....
First off, it should be said that in two separate places on the dryer, it says that it should only be used with outside venting for risk of fire, and since this was a big question I had, I feel it's important to start with that.  It's also important to check your lease agreement if you rent because you might be spending money only to have a maintenance guy tell you that it's not allowed when they come through and check the smoke alarms and they just happen to see it...

That being said, this little dryer works perfectly.  I use it in combination with a portable washer, and I find that if I keep the loads down to the size of the spin drum in the washer, the dryer will finish them off in under an hour.  Not bad at all for 110V.  It is a smaller dryer, so if you try to overload it, you risk damaging it, not to mention wasting energy because it will take much longer to dry.  I'm not really comfortable using the high heat setting with indoor venting in an apartment, but the medium and low settings dry everything just fine.  Solid construction, very sturdy.  I highly recommend!

Note: You may want to sit with the unit the first few loads just to make sure there wasn't a defect in manufacturing or unseen damage during shipping.  There is potential for a fire to start and very quickly get out of hand.  At about 20 minutes or so before the end of the cycle, the heating element should turn off and the exhaust should be room temperature.  If the dryer is still blowing hot air and the cycle finishes, unplug the unit immediately, take out your clothes if you don't already see a fire, keep an extinguisher close-by, and if possible, take the unit outside.  Do not try to use the dryer again and send it back.  This didn't happen to me, but I've read other reviews about the heating element malfunctioning and though there were only one or two, that's enough to be cautious.
