Bought one of auto expanders and it wouldn't stay it unexpanded.
Returned it to Costco for a refund. Prefer the old zipper type expandables, and also found the pull tabs on the Costco bags were plastic and not sure if they are up to the job for the long haul.
Long time Travelpro fan, but find their quality control and service have slipped.

So I'm looking for a durable and serviceable alternative. Would take an old style Costco zippered expandable if I could find one.
