Just want to give a shout out to Varitube for their wonderful customer service and all around great experience. Perry was extremely helpful with all my questions before my purchase and continued to be helpful 2 1/2 months afterwards. I had a problem with the switch/button on my sigelei zmax and he told me to send it to him and it would be taken care of, no questions asked. Received it back today and the switch is so much better than the original and am extremely satisfied. Thank you Perry and Varitube for such a pleasant experience.
