tl;dr: All (Renewed) items for sale here are typically listed as being in "Excellent" condition, but they likely are not. Buying from a Prime seller allows you easy returns and replacements for a DSi that is not in an acceptable condition.I've enjoyed playing DS games on my emulators and wanted to try the games out on the original Nintendo DS hardware. Due to my large hands and subpar eyesight, the DSi XL was the best choice for me. I've already searched all of the SF Bay Area and LA game stores for a DSi XL in great or mint condition. Right now, they are typically selling for $100-$130 for beaten up units with scratched screens to $130-$160 for semi decent ones with some cosmetic issues. I never could find a mint one anywhere, so I thought I'd give Amazon "Renewed" a try before rolling the dice with fleabay.Please read Amazon's descriptions for Renewed items, especially for "Excellent Condition" items: https://www.amazon.com/gp/help/customer/display.html?nodeId=202089470I ordered from Prime seller Cave Gamers an "Excellent Condition" Renewed bronze DSi XL. Please take a look at my photos tagged with "Item #1" to see the issues found on it. It obviously did not match Amazon's criteria for Renewed "Excellent Condition", so Amazon promptly offered to send me a replacement from the same vendor.The second DSi XL I received from Cave Games was filthy, but the shell was in much better condition once it was deep cleaned. The bottom screen however was super scratched up until I realized that it was just a screen protector. Once that was removed, both the top and bottom screens were scratch free. There is still a slight yellowing on the right side screen edges for both the top and bottom screens. Unfortunately yellowing screens are common on used DS & DSi consoles, so you'll have to hunt for one with a perfect screen. Photos of the second DSi XL I received are tagged with "Item #2".Issues found on "Item #2":* The battery would only last for about an hour of Mario Kart 7. "Excellent Condition" should have >80% battery life as per Amazon. I swapped batteries with "Item #1" and now Mario Kart can be played for four hours without exhausting the battery. Batteries in both consoles were OEM Nintendo branded.* The included wrong color (red) stylus was a $0.25 cheap knockoff made entirely with soft plastic that would stick on the bottom screen while sliding instead of gliding. I swapped it with the black stylus from "Item #1". It too was a cheap knockoff of a Nintendo stylus, but at least it had the proper tip so it could smoothly slide on the bottom screen and not scratch it up. I have recently replaced it with a Hyperkin bronze stylus to get the Nintendo OEM color and feel.* The glossy top of "Item #2" had quite a lot of small fine scratches and a few medium scratches. I used some auto detailing supplies and hand polished it. Most of the smaller scratches are gone, but the medium ones remain and are visible from 12" away.* The bottom screen digitizer must have been replaced on "Item #2". A harder than normal press of the stylus is required to register a touch. This is typical of the replacement digitizers from China.I decided to keep "Item #2" as it was (shrug) good enough. I likely overpaid, but I've been burned too many times ordering from Japan vendors with less expensive DSi XL consoles.Tips when purchasing one of these Renewed DSi units other than the obvious button press checks and game card runs:* Check for yellowing on the screen edges when turning on a DSi. It is more obvious during the initial boot up when both screens are white.* Insert a FAT32 formatted SD card (<=32GB) and use the photo app to store photos on the SD card. I purchased from a retro game store an almost mint DSi XL, but it was unable to read known good SD cards from other DSi consoles. You must have a working SD card to enjoy homebrew items.* Use one of the default apps on the DSi that has drawing to verify that the digitizer on the lower screen is picking up stylus touches everywhere on the screen.
