does everything I need it to

Was nervous about buying pre-owned but BestMobileCanada's inspection process gave me confidence. The 256GB variant showed up in good shape—minor wear on the edges but nothing that bothers me. Camera works great, performance is snappy. The 1-year warranty takes the risk out of it.

works but battery is weaker than stated

The phone itself is fine—camera's decent, display looks good. But the battery's dropping faster than I expected for "good" condition. Listing said 85%, feels more like 78% in practice. Still usable, just not what I paid for. wish the 32-point inspection caught that.

exactly what I needed

Picked up the 128GB and it's been solid. Screen's clean, battery holds up through a full day, and the price compared to buying new is hard to beat. Arrived within the 24-hour window too.

solid phone, looks almost new

Picked up the 128GB model and honestly impressed with the condition. Screen is clean, no scratches on the back. Battery's holding at 94% which is better than I expected. Arrived within 24 hours. For the price compared to buying new, this is a no-brainer.

budget option that actually works

Got the 256GB in fair condition and honestly it's perfect for what I needed. Couple visible marks on the frame, but the screen's intact and the software runs just fine. Saved myself a lot of cash compared to new. Can't complain about that.

does what it's supposed to

Bought this as a backup phone and it's been reliable. Screen looks clean, storage is plenty, and it handles my apps without lag. The 1-year warranty was a big factor in pulling the trigger on a used device. No regrets so far.

good value, no regrets

My first refurbished phone purchase. 256GB gives me plenty of space. There's a small mark on the left side I noticed, but honestly it's barely visible and the phone works perfectly. Saving $300+ versus new felt worth it to me.

solid phone, decent value

Pretty straightforward purchase. Got the 128GB model in good condition—a few light scratches on the back but nothing that bothers me. Runs smooth, battery's at 87%, and the whole inspection report matched what I got. Better than paying full price for a new one.

works fine but battery concerns

The 128GB in excellent condition showed up fast and the phone itself runs smooth. Battery percentage was listed at 87%, but it drains faster than I expected for something supposedly in excellent shape. Still functional for daily use, just not as impressive as I was hoping for at that price point.

impressed with the quality

Honestly wasn't sure about buying pre-owned, but this A78 showed up and it's basically pristine. 128GB, battery at 89%, and zero cosmetic damage. The packaging was careful, delivery was next-day, and the warranty gives me peace of mind. Way smarter than spending $200 more on a new one.
