I am really disappointed in this product after applying it to my phone. There are too vertical lines that go across the screen at the edges. The worst part though it the responsiveness of the screen now. I constantly have to touch things twice and some letters don't get picked up without hard presses multiple times. and swiping down from the top for the options is really annoying and unresponsive since the screen makes you unable to activate the touch response swipe mechanism.

Would have given it no stars if I could. The metal piece connecting the two rings just fell off the first time I put it on. I am size xs/s and I got the belt in small - didn't even need to stretch it to get it on.

I was crossing my fingers that the two collars I ordered would work. This is a four-Corgi household, and two of them bark a lot. One barks just to bark. So, when a neighbor (nicely and rightfully) complained, I did a lot of research and selected this brand. It took less than a day for Abe and Emmy to catch on once the collars were on them. Ah, "the sounds of silence"! It's a quality, sturdy product and being able to recharge it rather than buying batteries was a big plus for me. Two observations I'd like to share: (1) one reviewer remarked that the unit was too big for her small dog. Emmy is petite and 22 pounds, and the unit is a bit overwhelming on her neck, too. (2) The unit went off once when Abe shook his head, and once when another dog standing near him barked. Changing the sensitivity eliminated the unit going off when he shakes his head, but not when a nearby dog barks. All in all, this was money well spent!
