Product review (5 stars): Works fine
Had one before and it lasted for years before I cracked it.  One thing which is absolutely necessary, tho' is to get out and clean the lint which accumulates.  I do it twice a year.  Maybe more often with a bigger family.  It's not a big deal or a lot of hassle to do.  However, if you don't do it, eventually the interior "lid" will not raise to let air escape.
