I have three sets (of two) talkabout Motorolas. Costco impulse buys. LOL
Two 230s, two 330s, and two 355s (I think I got the numbers right).
I do know the all three sets, were all capable of communicating with each other over miles of hilly terrain in the Methow area.
Neither set had any issues at all. The 355s usually go with me if hunting with someone. I leave one in my truck and take the other with me when hunting solo. The other two sets I use camping and fishing, and I also lets the kids play with them.
All work great, especially for the price.
I won't say they are as good as the Rhinos, because I have never used a rhino. But I have heard great things about them, especially the friend locator on the GPS.
