    • This is an excellent radio Great features!
I’ve seen a lot of mixed reviews on this radio transmitter. I don’t know why anybody would say anything negative about it. It’s all positive everything works perfectly except for the phone mount. Bluetooth works great with the module that is an extra add-on. It’s worth it. You just have to set it up right you cannot access any good settings though it’s pretty basic speed RPM and heat voltage. I am not a robot. ... show more

These transmitters are awesome I bought 2 they are easy to use and comfortable and don’t feel like cheap toys. Although it would be great if it had a rechargeable battery instead of 4 AAs but it’s still good.
