Today I purchased a Radians Tac Ear for $45 (trying to save some money over the Walker Game Ear). I've already called the retailer and informed him that I will be returning it. The device makes a feedback squeal that can be heard everywhere in my house. No adjustment will make it go away.
I’m back to my original plan, to purchase a Walker Game ear. I still have my original dilemma, which one to buy. The prices of the different models vary from $130 to $400 U.S. Since I likely won’t be able to return a mail-order purchase conveniently, I would like to make the best choice up front. I’ll be doing more research, and will report back here if I learn anything.
