Freezes, crashes, and stalls. Bumpy organization. I still have to go back to my catalog 123 all the time just to find what I'm looking for. Look, the app was a good try and would have been maybe adequate had it mimicked the website, but as an app, it's a failure. Bring back the printed catalog. It was an institution, and it's still the most important thing near my desk.

I'd rather have my little yellow book. It's more legible and I can go back and forth between a group of pages with a few paper clips. Navigation on this site is slower and only works between two pages. For detail information the book is easier (for me). That's why this site is just"OK". Can I order a book to use to collate my order, then use the site to adjust pricing and place my order? Or has the cost of printing forced my favorite source book out of publication?

Ap won't load the specific item data when I do a search. If I Uninstall the ap and use the web page it woks just fine. I have an s10e. I have other aps with the same issue so it's a programming issue using an older operating system. I've tried rebooting my phone. Uninstalling and re-installing the ap with no luck.
