The back glass I was assured was legit Apple product and when I went to get the front screen replaced at a different shop they applied a little bit of pressure and it shattered so that shot ended up replacing it for free and told me that the parts used on the previous repair were low quality. The original repairs cost me 320. shop around people there are better options as far as price and quality. I ended up getting everything fixed at that Little kiosk on Hamner in Norco that's shaped like a cell phone. Edit: I never stated that I dropped my phone. I only say I take responsibility because there was pressure on the screen from the battery and when I got to the Apple Store I pulled it out of my pocket and it was cracked. The parts used were low quality

Nilda made everything so easy and stress free! I kinda dread these types of errands. In the past,…read moregetting a new phone was like buying a new car, but just a little less excruciating. Today, we got in and out in about 30 minutes. Upgraded my son's phone, activated/transferred the data, and did all the stuff in no time that seemed to take hours in the past. Upon entering, we were greeted immediately. No wait! There were ample employees and the store itself is calm and big. Nice colors, comfy, and great music playing as well. Definitely not a stressful and crowded environment. Nilda instructed me to log in to my account on my phone and then walked me through the trade-in and upgrade steps. I paid the activation fee on my phone as well through Apple Pay, and then she went to get the phone. Next came transferring the data and we were out the door! Seriously, I can't believe how pleasant the whole experience was. I'll be back soon to upgrade my own phone. Nilda is the best!

From the moment I walked in, Siman and Dom took the time to understand my needs, explain my options clearly, and help me upgrade my phones without any pressure or sales gimmicks. There was no bull, no unnecessary upselling, and no attempt to steer me toward products or services I didn't need. Instead, they focused on creating a true win-win experience. Their product knowledge was exceptional, and they helped me maximize the value of my upgrade by ensuring I benefited from promotions that included an Android smartwatch and a Harman Kardon portable Bluetooth speaker. More importantly, they patiently answered every question and made sure I fully understood my options before making any decisions. What stood out most was their professionalism, honesty, and genuine commitment to customer satisfaction. Siman clearly leads by example, and Dom is developing into an outstanding representative under his mentorship. Together, they represent the kind of team that builds long-term customer loyalty and trust. As a customer, I left feeling respected, informed, and confident that I had received the best possible service. That is not something I say lightly. If you're a T-Mobile customer looking for a seamless, straightforward, and genuinely enjoyable experience, I highly recommend seeking out Siman R. and Dom L. at the Ontario Mills T-Mobile store. They have earned my highest recommendation and a well-deserved five-star rating. Outstanding job, gentlemen. Thank you for proving that exceptional customer service is still alive and well.

The Vision Pro demo couches, big skylights and the video wall from the first renovation may be gone, but a refreshed design to this store is much better to our local Apple community. I also had a chance to meet with Apple executive Vanessa Trigub vice president of retail at the door as I high fived and greeted the employees after I temporarily went to Brea mall store during summer break when this location was closed. I also got to meet corporate including Órladh Seddon of Retail Merchandising Ops from Apple Los Angeles in this grand reopening. Plus new faces and the ones I rly remember seeing before the remodelling- specialists Jay, BT, Pete and Tim, and manager Christina as the procession of customers made their way through this comeback opening. I also was the first few people to sit in the new Genius Bar! It's much wider and bigger than the old one before a video wall took it down in 2018- and did my Apple Watch Series 6 battery replacement there. Plus spoke to an iPhone 17 pro user on the Genius Bar that was also the first one to check it out on her iPhone boot looping issues and also the store feels more wider given that they took down the old countertops of wood and the metal walls for stone walls. Still amazing and friendly staff as pre-renovation was. I also got my reopening pics and videos on LinkedIn and Macrumors featured!
