Hiya everyone. Just wanted to pop in. hey Vulcan, you may be right about the 3.7. The 4.0 are too strong on some juices. So my hubby lost his 3.7 650 MAH. I made sure he didn't steal mine then..... Bwahaha.
I have the very same experience, Lori. The 4.0 burns the juices sometimes too...and I too love mine.
