excellent condition, great value

Honestly impressed with how clean this phone looks. No scratches, screen has no marks, and it feels practically new. The 32GB is tight if you use lots of apps but manageable. Battery's holding strong at 89% health. Way cheaper than buying new and you can't tell the difference. Warranty gives peace of mind too.

solid phone for the price

Got this A21 a few days ago and honestly it's been solid so far. Screen is clean, phone runs smooth, and the 128GB gives me plenty of space. I was worried about buying pre-owned but the inspection report they provided was detailed. Came with the charger too which was nice. For under $200 this is a good deal.

does what it needs to

It's a decent phone. The 32GB storage is enough for my use, camera's fine, battery gets me through a day without issues. My one complaint is the screen has a few light scratches that the listing should've mentioned — they don't affect use but I wasn't expecting them at this price point. Still happy with the purchase overall.

surprised how good this is

Was skeptical buying refurbished for the first time but this changed my mind. The A21 is snappy, screen looks great with no dead pixels, and the 32GB is enough for what I need. Came in pristine condition. The 24-hour delivery promise was actually true. At this price point it's genuinely hard to beat.

works great despite the cosmetic wear

Knew I was getting 'fair' condition so the scuffs on the back don't bother me. What matters is the 128GB storage and performance, and both are solid. Battery sits around 88%, fast enough for daily use. Better value than I expected considering the warranty covers me for a year. Happy with this purchase.

battery died after two weeks

Arrived in excellent condition physically, but the battery health was way below what was listed. Started at maybe 60% capacity, died completely after 14 days. Contacted support and they honored the warranty, but it's been three weeks waiting for replacement. Feel like I got unlucky with this unit.

does what it's supposed to

Device had some visible wear on the back but it's exactly what the 'fair' condition listing said. Battery holds a decent charge, camera works fine, and nothing's broken. Showed up in two days. I'm using it as a backup phone and it's doing the job without complaints.

reliable phone, no surprises

Grabbed this 128GB A21 knowing it was in good condition and it's exactly that. Screen's clean, back has minimal marks, looks almost new in person. Battery's at 91%. It's not flashy but it does everything I need without fussing. Good value compared to retail, and the warranty gives peace of mind. Would order from BestMobileCanada again.

screen looks good, phone feels sluggish

The device showed up fast and the 32GB model looks fine cosmetically. Good condition overall. But it lags constantly when I open multiple apps and the listing said it was tested thoroughly. Not sure if this is just normal for the A21 or if something's off. Performance-wise, I'm disappointed for the price.

works fine but battery concerns me

The phone itself is in excellent shape—looks almost brand new—and runs all my apps without lag. But the battery's already showing 81% health after a few weeks of regular use, which seems low. Might need replacing sooner than expected. Good device otherwise, just a bit worried about longevity.
