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

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.

I purchased this Samsung S21 Plus that was refurbished supposedly to excellent condition. It was the delivered on September 16th 2024. Today I am writing this review and it is September 28th 2024. This morning I got up like every morning and picked up my phone to check emails and messages and was on the phone for approximately 5 minutes when all of a sudden the screen went black. I can hear the buttons functioning when I touched the black screen but could see nothing. I have the exact same phone which is my old one that still works so I put them side by side and used my phone as a guide for the positions of the buttons on the phone with no screen. After turning the phone on and off several times and recycling it still no screen. Took the phone down to repair center and they told me the display is shot. I could not send the phone out back to Amazon because it has all of my data and information in it personal and Financial. Therefore, I was forced to pay the repair center $200 to replace the screen. The short of it is, I would be very careful with this company. Obviously they do nothing with the phones except clean them up replace some aesthetic parts and put them in a brown cardboard box and ship them out. I wasted 275 on this phone when I could have bought a brand new one for an additional $100 off of eBay in a sealed box. The moral of the story is don't try to cheap out. More importantly I would definitely rethink buying from this vendor because their products are substandard.

Definitely not excellent condition. It's all dinged up but the screen is flawless and a case will cover the rest. So far it works well.

Purchased : May -8 From Seller : THeGadgetdeals A lovely phone for my daughter's birthday present. After three months of use, the phone still functions well and performs as expected despite a few minor scratches that are easily covered by the phone case. The camera is excellent, and the battery holds charge well.

this is the second phone i bought from this seller, both phones were in great shape with not one scratch on them. i initially thought there was a problem with the second phone because it wouldnt make or recieve texts or calls but it turned out to be an issue with att and they resolved the issue. the seller contacted me the same day i messaged him with my issue and was going to help me get it figured out, but i had already contacted att before i saw that he messaged me back. i would recommend this seller to anyone!
