I thought was a mistake! The faceplate looked like one of those phony tottler phones-icons pasted on plastic. I was delighted to find that was only outward appearance-as was the almost weightlessness. The depth was adequate-too much for some areas-I ran at only 3 bars sensitivity with 4 bars in some places! I surely wasn't expecting the two rings! Will checkthem out after work. The notch worked g?eat but took a few minutes to figure it out despite the instructions-yes I read them. The disappointment? NO last use memory-you have to reset from default. Once you find out it's not a toy-it's a great buy!
