It was at a great price as you have to watch every day almost every hour for a price change and when it does you better get it quick because for the price and what it looks like makes it worth the wait on back market as it worked well with no scratches

I recently snagged the Samsung Galaxy S21 5G from Back Market, and it's been a game-changer. This refurbished gem looks and feels brand new, and I couldn't be happier with the experience.

Always feels good to buy a refurbished product that's been given new life vs a new one. The phone itself is great, but the battery life is less than average. Otherwise no complaints.

Phone is a described which is excellent condition. I have switched everything over from my S8 and all is working perfectly. I was very skeptical about refurbished but after doing some research I decided to order. I am very happy with my phone and will look for other refurbed items.
