Has anyone used this radio yet? I've been looking to find a cheap radio that has some important functions like exponential, steering dual rates, and end point adjustments which this Cougar PS3I does have. The other 2.4ghz radios that I found in this $100 don't have any of these functions, especially exponential which is very important to me.

If you've used this radio how do you like it? We have tried some other cheap radios but the response was very slow to the car and it gets glitchy when theres only a few more 2.4ghz radios around so I'm wondering if this radio has the same issues.
