The V3 Flip is really a beautiful device but doesn't even work as well as most clones. The Voltage drop on them is outrageous. Plus the fact you can't buy a clone so you're spending well over $300 (unless that's what you're looking for). But really if you're looking for a good mod there are plenty. The Changeling clone I have by Vapetech is amazing. Also the Vapetech Pegasus. As everybody else in the thread stated the SXK stingray x is always a winner too.
