We have now purchased two of these kennels.  One for a chinese crested and one for a cockapoo.  They have worked perfect for housebreaking and kenneling while I'm away.  They fold up great for traveling as well.  I have always used the plastic ones but prefer the wire crate.  I just drape a blanket over the sides to give the dogs a little privacy.  They love them just as much as I do!  The only negative is that with the larger size it is a little more difficult to carry with the handle when opened up but this is almost never necessary.
