I just tried the Primos Alpha Dogg caller for the first time yesterday. I test all the products I sell but I had not had a chance to use this caller yet. In short, I had a limited amount of time so I took the caller out of the box, stuffed some batteries in it, flipped through the menu and went hunting. (I'm not particularly techy so this is saying something.) On the first stand, I called the biggest coyote of the season into shotgun range and dumped him at 25 yards if a testimonial is worth anything.

The photo doesn't do this dog justice. He had long, beautiful gaurd hair--really a nice coyote.
Review-wise, the caller has a well thought out design. The speakers fold in and the legs fold up. There is a remote anchor on the back of the caller. The remote was very easy to use. All the functions should be easily manipulated even with heavy winter gloves on. (The remote functions are easier to work than my Foxpros IMO.) It has two "hot" buttons for preprogrammed sounds. It comes with a Pup Distress sound as Hot #1 and some Rodent Distress as Hot #2 to use as a coaxer.
The speakers seemed to be comparable to the Foxpro Spitfire and Wildfire as far as fidelity goes with more volumn. The sounds themselves however had a hollow sound to them like they were recorded in a bathroom. The unit is capable of using MP3 files and other recordings so it would be interesting to try some other files in it to see how they compare. (Note that the coyote I shotgunned didn't seem to mind the fidelity of the speaker system. lightbulb ) It seemed that the legs and hinges may not stand as much abuse as a single piece unit but time will tell on that.
That is my take on the caller so far. Fire away with any questions. I may or may not be able to answer them at this point in time.
