I don't have a v2 but I have a v1. I also have an ipv3 and they are both good
devices. The Hex you have to dial it in by feel and get a feel for when your batts are low, comes with a lifetime warranty and I love it. The ipv3 is also a good
device with a good chip. I have had zero functional issues from it and I am glad I have one. They both have their place in my bag of trix.
