I have the Buzz and have nothing but praise for it. Battery life is very long, size is good (larger than BB, smaller than SB), the ability to adjust is great as it allows me to use all my attys now. 6V was kinda strong and sometimes burnt but not with the Buzz. I have never spent that much on a
mod and was hesitant over getting it. I am so glad I did.
Not one problem at all with anything and support is instant.
I could not see spending 170.00 for any
mod, especially if one is 50.00 cheaper and does the same thing.
I don't want to make negative comments on something I don't own, but check out complaints and I think your question will be answered.
