Yes. If a collapsible reflector potato chips on you (as those with poorer build quality will do), it becomes practically worthless as a reflector. I've had zero problems with Photoflex reflectors warping, but I've had both eBay and even Westcott reflectors do that to me.
I personally prefer Reflectasol umbrella/reflectors. I've got half a dozen of them, mostly 36-inch square. They last forever and stay perfectly flat; they fold like umbrellas, so they're even more compact than the twistoflex collapsible style--it takes no fancy magician tricks to get them closed; the fabrics are interchangeable and dry-cleanable; a halfway decent seamstress can even make more fabric. Reflectasols are pricey new, but there are usually good deals on used Reflectasols on eBay (as I said, they last forever).
I've recently purchased a couple of Interfit panel reflectors that I also like quite a bit. Although they're "dismantlable" rather than foldable like Reflectasols, at least they assemble and dismantle quickly and quirklessly. http://www.bhphotovideo.com …Panel_Reflector_with.html
