Quota bear call

[flytrue]

I am in Norcal and have a bear tag in pocket. I have a handful of predator calls. Some of them have called in a bear, by accident. I have recently viewed a bunch of videos of guys calling in bears with something called the Quota Call. This is happening in my neck of the woods. It seems to do the trick. I am tempted to order one but the price seems steep, ($37), and I am hesitant to order one, thinking that it's probably just as good as the calls I already own and use.
Anyone have any firsthand experience with these calls? I can hunt bear without a call but calling one in is fun!
