Are Lékué steam cases any good?

I have a small case. I used it for travel when I was on a very restricted diet. You can easily prepare chicken and vegetables in a hotel kitchenette. I stopped using it, mainly because I stopped needing to travel and got off the restricted diet. But once, at a destination wedding in Park City, Utah...all the guests were invited to a small potluck with the food we had in our hotel rooms. I brought chicken breast over a bed of arugula...and everybody thought I'd actually poached it on the stove.

i would say No. A cheap folding metal perforated steamer insert works great.
