Product review (3 stars): How cheap can you make something?
I had a very nice device just like this many years ago but it finally bit the dust.  The alleged lint filter is a LADIES ANKLE SOCK.  The plastic is rigid and thin so be very careful not to crack or break it when you install it.  This will do the job but I'm sure we will be shopping again soon.  Perhaps with several rolls of duct tape we can get it to last for a while.  Made in Canada so I'm pleased to be purchasing on our continent, but I don't believe you can make it any thinner or cheaper.  We will not buy this again.  The distributor did ship quickly and it does weigh about 1 lb 6 ounces in it's cardboard shipping box so the shipping price on target.
