    • Samsung Galaxy S21 + 5G
Service provider: Unlocked Color: Phantom Violet Size: 128GB
The Samsung Galaxy S21+ 5G is an excellent phone. It's very fast, apps open smoothly, and performance is fluid even with heavy use. The screen is large, bright, and has very sharp colors, ideal for videos and social media. The camera takes high-quality photos and videos, even in low light. The battery lasts all day, and the 5G connectivity is a great bonus. Overall, it's a reliable, modern phone with a sleek design. I'm very satisfied with the purchase and highly recommend it. ... show more

    • "Exceeded my expectations"
Service provider: Unlocked Color: Phantom Black Size: 128GB
I've been using the Samsung Galaxy S21 Plus for a while now, and I have to say — I'm really impressed. The phone not only looks premium, but it also feels amazing in the hand. The sleek design, slim profile, and matte finish give it a very modern and elegant touch. It definitely stands out without being too flashy. One of my favorite features is the camera. The photos are incredibly sharp and full of detail. Whether I'm taking pictures during the day or at night, the results are consistently great. The camera app is also easy to use, and features like portrait mode and ultra-wide shots make it super fun to take photos. The video quality is just as impressive, especially with the 4K option. The display is another highlight — large, bright, and very smooth thanks to the 120Hz refresh rate. Everything from scrolling to watching videos feels really fluid. Overall, the Galaxy S21 Plus is a fantastic phone. If you're someone who loves taking high-quality photos and appreciates a stylish design, this device won’t disappoint ... show more

    • It's a new phone to me.
Service provider: Unlocked Color: Phantom Black Size: 256GB
I used to go to Back Market for ALL my Samsung Galaxies and accessories. Everything I own practically came from the 2nd-hand store, why pay top dollar when I don't need to, until I read their reviews recently, that is. They seemed to have gone downhill since I last ordered my previous S105G phone. I heard good things about Amazon's refurbished equipment, so I thought to give it a try. I'm glad I did too, because I couldn't be happier or more satisfied, so far. The phone is in beautiful shape with no defects, looking brand new, for a much better price than buying brand new, saving Hundreds of dollars. Talk about a cheap upgrade, why isn't everyone doing this? There's so much waste in the world, why should I contribute when I don't need to? Saving a lot of money in the meantime, and I'm all about that. It's kinda like being a smart consumer and buying a pre-owned automobile for the savings and sanity. So far, the phone is treating me well and I have no complaints. I was very surprised at the speed of delivery, especially when your phone's battery is dying slowly and barely keeping a charge. I love my new(used) S21+5g, which is old in terms of computer/electronic equipment. But a major step up from the S105g I was using. Faster Everything. I'm a happy camper and will NEVER own or buy a brand new device, due to the outrageous pricing out of the gate, especially for a quality phone. This phone's system is a major upgrade, to me. Even though it's years old in operating systems, which I can't tell, it's a way better system than I was using and is smarter. An excellent-condition phone, with way more capabilities for pennies on the dollar, is a smart move in my book. I just hope nothing goes wrong. But if it does, it's not a thousand plus dollars, I'd be out just a couple hundred, comparatively. Satisfied to the bone, I am, and no one is gonna tell me differently. The phone sounds good and is built to last. Thank you, Amazon, for coming through legitimately and without breaking the bank or ending up owing money every month on some brand-new device I don't need. Just because the wastful companies of the world have to be making them a new system evey year, don't mean I have to break myself to have one for no apparent reason other than "keeping up with the Jones's", to have one, only for it to be outdated in a year, before I'm done paying it off. No thanks, I'll take my chances with refurbished, and now, most have an insurance plan for a couple of dollars a month, which helps ease the burden of not knowing what you may run into either. ... show more

    • Works well. Just wish battery was better.
Service provider: Unlocked Color: Phantom Violet Size: 128GB
Ordered as a replacement after my old phone suddenly stopped working. If I didn't know any better, I would not think it was used. It still gets all the proper software updates. I like the amount of storage (though I miss when Samsung phones still let you add a memory card to expand). Charging is relatively quick. Though the battery life leaves something to be desired. ... show more

Ended up buying this phone on Black Friday Sale. After reading through the other reviews I was beyond scared that the phone wasn't going to be great like the ad says. Showed up very fast, an to my surprise whenever I opened it the phone looked amazing. No scratches on the screen, nor the back glass. It was so easy to switch from my old phone to this phone in a matter of seconds. Bluetooth an Wifi works an connects without any issues. I have notice that the battery life felt like it wasn't holding a charge until I found that I was using an older cord than the original cord that came with the phone. Ended up switching it out an it charges so fast an lasts almost all day with a full charge. I will have to add that the only flaw that I had with this product was a few scratches right beside my camera area, but it doesn't caused any problems with the back camera's. ... show more
