TL;DR: Very happy, phone as described on website, no unexpected issues
Having previously owned a Pixel 6 Pro, I knew what to expect from the phone itself. What I didn't expect, was the genuinely good quality of the phone, that was exactly as described, if anything maybe slightly better.
The only issue that I have, is that I am a *very heavy* phone user, and while the battery is good enough, it is showing as having around 10% of battery capacity loss compared to new, but this was expected, as the battery hadn't been replaced, and was mentioned on the listing.
At some point, I will likely replace the battery in the phone, which will definitely extend its life even further.
I will definitely be a returning customer to BackMarket, and will be recommending the site and service to friends and family who are looking for a budget, eco-friendly option when it comes to tech.
