I got a chance to use one the other day when I went out with my buddy. Overall I liked it. I like that you can point the speakers in any direction you want. I have the CS-24 and I think the Shockwave might be a little clearer, but the CS-24 is way louder. I like the carry handle as compared to the cheesy one on the CS-24. The new remote is great and I like a lot of the new features. I am pretty sure the temp was never correct as it said over 70 a few times and I can assure you it never got over 45. If I had to choose one of the two though I would get the new CS-24C I think it is with the new remote. Either way they will both bring in coyotes.
As you can see it works called in 2 doubles and a triple with it this day.
