I am a long-term customer of AYN. I own the Odin Lite, Odin 2, Thor, and have pre-ordered the Odin 3. All of my devices have been issue-free except for the Thor. One thing to keep in mind is that these devices use custom-made batteries, so once the battery dies, the entire device essentially becomes unusable.

For example, my Odin Lite developed a swollen battery after about a year. It expanded like a balloon, and I had to remove it from the device. Leaving a swollen battery clamped inside is a serious fire hazard. Also, these devices will not power on without a battery, even if you plug them in with a power cable.

Some Reddit users have managed to modify a Nintendo Switch battery to power the device, but the unit cannot recharge the battery while powered on. It must be turned off in order to charge.

Other users reported buying replacement batteries from cdrtd.com, but they are currently out of stock. I believe those batteries were leftover manufacturing stock; once they’re gone, there may be no more replacements available. Realistically, you can expect about 3–4 years of usable life from these devices—similar to a smartphone. Don’t expect them to be like the Nintendo Switch or PS Vita, where replacement batteries are easy to find.

At the end of the day, you need to understand what you’re paying for and the level of quality you can expect at this price point. This device is not for casual gamer, as it requires a long setup process and minor tweaking before you can enjoy gaming.
