For starters I'd like to say thank you to mayflower for the extremely fast shipping. I see other reviews here and I can say I haven't had the same bad experience that some of you have had. Mine came in perfect condition and works as advertised. It's very a few weeks now and I've played about 70 hours on mine. It works and it works good. No issues. Battery capacity is normal, sd card slot works. I haven't tried out the actual game slot yet but I'm very confident that it works too. This is a good replacement for sure. Keep in mind folks this is the V1 2017 model not the V2 2019 model. So make sure you double check which replacement you are getting. I thought I wouldn't care about which model I got and I definitely should have opted for the V2 simply for the extra battery life. Overall, I am happy with this product.
