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.

Like McMster itself, the app just works. No flashy graphics or sounds, just quick easy ordering.

The app is really great! I like the addition of spec fields in the top for easy deselection if I accidentally click on a spec I didn't mean to. It's been really useful to be able to browse and buy parts on the go rather than having to be at a computer to do so. Great job to the app team! If you've ever used competitor apps you'll know what I mean when I say this app is worlds above theirs!
