Overall, worth the money and good to have as a secondary call.
Pros: Super easy to use, my 3 year old can make some very realistic purrs and clucks with it. The full yelp is very, very raspy (sexy for Mr. Tom). The volume control is a great feature and you can change the pitch as well. I have used it in light rain with no problems at all. The clucker button is convenient and sounds pretty good.
Cons: The design has changed slightly over the years and the main plunger is not as comfortable/ergonomic to use for hours, a little sanding to round off the edges is nice. Biggest complaint is that you can hear the spring pretty loudly if you're not extremely gentle on release. You can work around it but it takes some practice and I don't see myself using this too much in very close contact with turkeys. Each has a slightly different tone, not consistent but that can be a good thing.
If you are going to buy just one call and are strapped, this is worth picking up. Has some features that knock the socks off of other push-button calls.
