We had the Chuckit 18M Pro model before we bought this one and we loved it, but our dog got a hold of it and chewed it up, so we bought this one to replace it because it was a bit cheaper than the pro model. The one we received is a fun green color and fits all chuck it balls and tennis balls in it just fine. This one does the job, but the handle is shaped a bit different, so you have to get used to throwing it a bit differently than the Pro style. The only thing I really don't like about it is that the handle feels flimsy compared to the Pro model. It bends really easily, especially when picking up the ball and I'm worried it's going to break in half. Other than that, it works just fine. I like the length of the 18M styles; the length is perfect and can go a really good distance. If you have the extra bucks to get the 18M Pro, I probably would, but if you need to save a few bucks, this one would do just fine.
