First of all, remember that we are talking about a four-year-old tablet, almost five years old. But still, for 99 euros along with the genuine case, it is a sudden gift.
Does it lag? No, unless you're watching Netflix, downloading an episode of Wheel of Fortune in HD, and have YouTube playing Prince in the background.
Is it fast? In reasonable terms, considering the 4-5 years it has behind it.
Does the battery last? With 4800, how long can it last? You have enough options in the settings to increase its duration. Whatever you do, you will definitely have it for a day. There is also a strange option called "Smart Battery Capacity" that reduces the battery's duration but increases its lifespan (at least that's what it says).
Does it support Google Play and Netflix? Yes, both. I should note that newer models of the same brand do not have Google, which is important for games.
Does it take good photos? If you find someone who takes photos with a tablet, show them to me as well.
Does it have good sound? All of Karajan's recordings were made and played with a tablet.
Does it support wired headphones? Yes.
Does it play all games? It depends on the game's manufacturer. Games with motion, colors, running, etc. may not be playable or enjoyable. Even a simple match-3 game can be challenging if it is designed with many effects for visual appeal. However, I had exceptions where rally games played normally. In general, if the purpose of purchase is solely for games, you should definitely spend more money.
As for the disadvantages, it does not support Android upgrades, and anything you download goes ONLY to the main 32GB memory. However, I added a 32GB memory card and it works fine, of course, only for photos, videos, etc. I also tried connecting a flash drive, and it recognizes it normally.
Update June 2023: Due to the inability to upgrade its Android, several games will stop working, not only because of the tablet's capabilities but also because of the Android version. Additionally, since any mobile phone, even those priced at 70 euros, has greater capabilities, browsing will feel extremely slow.
Should I buy it? If you know that you get what you pay for, if you don't rely on constant browsing, if you want it for your 10-year-old son, if you want it as a GPS screen in your car, if you want it for watching Netflix, if you want it for your wireless camera, etc., then yes, get it. Just remember that if you want to move up a class, you have to dig deep into your pocket.
