Helicon, Axiom's V4 products are not the same as the V2 or earlier products that you read criticisms of. Like I said in my reviews, I've been watching what's been going on in Dwight a long time now and I felt the enhancements in the current products reflected significant advances in engineering maturity. I have absolutely no complaints and only heaps of praise about the 160v4 and EP800v4 and I have to say, that is quite unusual for me. smile
