I just got an iPhone XR around Dec 2019. Thanks again for the quick delivery. Not really sure what to purchase next but I would not recommend this shoe to anyone in the food service industry. Im soo glad I didnt let other bad reviews deter me, and the one with the rack leaning completely to the side, I believe that was improperly put together. Kudos to Feedback Sports for the design and quality of this great tool, its well built with quality and durable materials, versatile, compact, practical and, above all, provides very accurate results. Just a note--the uppers on the original pair are still in excellent condition. I even banged on my desk during a test call and my coworker did not hear it. But you soon get used to it. But come January 2021 T-Mobile subscribers will only be able to make VoLTE calls. They were easy to put up too.
