True, you have to go up to $120 for the 25m version, or $450 for Unitree's L2 which gets 30m in 3D. That's about as much you could possibly ever need unless you're making high speed vehicles that need more reaction time. In which case you probably shouldn't be relying on the cheapest thing on the market :)
