    Still have not received it

    I would like to review this product. To tell you how happy I am with it. But I can’t. Evaluate after waiting weeks and weeks. I still have not received it. So hurry up and ship the thing mate. Or give me a shout out on the bloody dog and bone

    Love it

    Be prepared to add a different connector to your existing throttle. Not very difficult, if you have something that will crimp a ctx50 it will be even easier. everything else was very straightforward.

    Shipped fast from uk to ak! and came with more than enough hardware, I appreciate spares.

    The new grommets on the controller itself seem much better than earlier models which is a big plus as well.

    Very happy! Can't wait for spring to try it out.
