If you're not a Spektrum user though, Lemon won't work. Or if you already have Spektrum satellites or receivers the price is pretty close.
The fact that it has clear, well written documentation, and has a setup process that's so intuitive is a huge step up from Lemon.
Don't get me wrong, I fly lemon myself, but there's definitely a market which will pay a premium for a product that's easier to use. Lemon are good, but they rely on the community for documentation, and they're definitely a bit complex to setup.
